General safety information and precautions
The following safety precautions are intended as a general guideline for using PLC systems together
with other equipment. These precautions must always be observed in the design, installation and
operation of all control systems.
m
DANGER:
● Observe all safety and accident prevention regulations applicable to your specific application. Always disconnect all power supplies before performing installation and wiring work
or opening any of the assemblies, components and devices.
● Assemblies, components and devices must always be installed in a shockproof housing fitted
with a proper cover and fuses or circuit breakers.
● Devices with a permanent connection to the mains power supply must be integrated in the
building installations with an all-pole disconnection switch and a suitable fuse.
● Check power cables and lines connected to the equipment regularly for breaks and insulation
damage. If cable damage is found immediately disconnect the equipment and the cables
from the power supply and replace the defective cabling.
● Before using the equipment for the first time check that the power supply rating matches that
of the local mains power.
● Take appropriate steps to ensure that cable damage or core breaks in the signal lines cannot
cause undefined states in the equipment.
● You are responsible for taking the necessary precautions to ensure that programs interrupted by brownouts and power failures can be restarted properly and safely. In particular, you
must ensure that dangerous conditions cannot occur under any circumstances, even for brief
periods.
● EMERGENCY OFF facilities conforming to EN 60204/IEC 204 and VDE 0113 must remain fully
operative at all times and in all PLC operating modes. The EMERGENCY OFF facility reset
function must be designed so that it cannot ever cause an uncontrolled or undefined restart.
● You must implement both hardware and software safety precautions to prevent the possibility of undefined control system states caused by signal line cable or core breaks.
● When using modules always ensure that all electrical and mechanical specifications and
requirements are observed exactly.
● At power ON/OFF, current may instantaneously be output from the output terminal of this
module. In such case, wait until the analog output becomes stable to start controlling the
external device.

Overview
Overview
This User's Manual describes the specifications, handling and programming methods for the HART
analog output module ME1DA6HAI-Q (hereinafter referred to as the ME1DA6HAI-Q) which is used
with the CPU modules of the MELSEC System Q. The ME1DA6HAI-Q is exclusively used for current
output.
1.1
Features
Multi-channel analog output is available.
By using a single ME1DA6HAI-Q, analog current outputs of 6 points (6 channels) are available. Standard devices with 4 to 20 mA or 0 to 20 mA input range and HART devices can be connected to the
module at the same time. The analog output range of the ME1DA6HAI-Q is selectable by the intelligent function module switch setting in GX(IEC) Developer.
HART master function
The ME1DA6HAI-Q can communicate with up to six HART-enabled devices. (One HART device connected to each channel.) HART* is a bi-directional industrial field communication protocol used to
communicate between intelligent field devices and host systems.
For this communication no additional wiring is required. Additional device information is communicated using a digital signal that is superimposed on the analog signal. The digital signal contains information from and to the device including device configuration or re-configuration, device status, diagnostics, or additional information.
The ME1DA6HAI-Q can operate as a HART master with protocol revision 6.
* HART stands for Highway Addressable Remote Transducer. Fore more information about the HART protocol please refer to
section 3.3.6.
FDT/DTM function support
The FDT/DTM* can be used for setting and monitoring the HART devices. To use this function, the
HART device must have DeviceDTM.
* FDT stands for Field Device Tool and DTM stands for Device Type Manager. FDT/DTM is a communication technique for the
manufacturer-independent configuration of processing systems at a field bus.
High accuracy
The accuracy is as high as ±0.3 % over the specified operating temperature range for the MELSEC
System Q.
Easy changing of the output range
The output range (4 to 20 mA or 0 to 20 mA) can easily be set from the GX (IEC) Developer.
Analog output hold/clear function
This function is used to set whether the analog output value will be held or cleared when the PLC CPU
module is in a STOP status or when an error occurs which stops the PLC CPU.
Warning output function
A warning is triggered if a digital input value falls outside the setting range.
Rate control function
The increment and decrement of the analog output value per conversion cycle can be restricted.

a disconnection.
Short circuit detection function
When the analog output current is 4 mA or more, the external load resistance is watched to detect a
short circuit.
Scaling function
The digital input value range (Un\G1–Un\G6) can be changed to any given range between –32768
and 32767, and digital values within the range are converted to analog values.

Analog output HOLD/CLEAR function
For the case where the programmable controller (PLC) CPU is placed in STOP or in a stop error status,
whether to hold (HOLD) or clear (CLEAR) the analog output value can be set.
Make the setting in the HOLD/CLEAR setting of the intelligent function module switch (please refer to
section 4.5.2).
Depending on combinations of the HOLD/CLEAR setting, the CH output enable/disable flag (Y1 to
Y6), the analog output range setting and whether HART communication is enabled or not, the analog
output status varies as shown in the following tables.
NOTE

The offset value for the 4 to 20 mA range is 4 mA. Output currents lesser than 4 mA will be overwritten with a higher value (4 mA) in case of e.g. "PLC CPU stop error" (refer to the following table).
Therefore for output currents lesser than 4 mA it is recommended to use the 0 to 20 mA range.

Detailed Description of the Module
NOTE
Functions of the HART Analog Output Module
The following conditions should be satisfied when the analog output HOLD/CLEAR function is
used on a MELSECNET/H remote I/O station.
● The master module of function version D or later and the remote I/O module of function version
D or later are required.
● Validate the station unit block guarantee of the send side cyclic data. (Refer to the Q Corresponding MELSECNET/H Network System Reference Manual).
● The setting for holding the output in the case of a link error must be made in the column "Error
time output mode" in the I/O assignment setting (Refer to section 4.5.1). The HOLD/CLEAR
setting by the intelligent function module switch is invalid.
This setting is validated on a per-module basis, and is not made on a per channel basis.
Therefore, to make the output status at a stop error or STOP of the programmable controller
CPU matched with the output status at a link error, set the same HOLD/CLEAR setting to all
channels (Refer to the table below.)

An analog output test is enabled by the output enable/disable flag
To conduct an analog output test, perform the following operations in GX Developer device testing:
● Set the output enable/disable flag (Y1to Y6) for the channel to be tested to "Enable" (OFF → ON).
● Write a digital value equivalent to the analog value to be output in CH digital value in the buffer
memory (buffer memory addresses Un\G1 to Un\G6, refer to section 3.5.2).
3.3.3
Rate control function
The increment and decrement of the analog output value per conversion cycle (10 ms) are restricted
to prevent a sudden change of the analog output value.
The rate control can be enabled or disabled for each channel by the rate control enable/disable setting (buffer memory address Un\G46). To enable rate control, write "0" to the bit position corresponding to the channel number and turn ON the operating condition setting request (Y9). As default, rate
control is disabled for all channels.
The increase digital limit value and decrease digital limit value are set in the buffer memory addresses
Un\G70 to Un\G81.
If HART communication is enabled the rate control function is applied to before the output signal is
filtered by the FIR filter.

Functions of the HART Analog Output Module
Scaling function
The scaling function can be enabled individually for each channel by setting the corresponding bit in
buffer memory address Un\G53.
With this function, the input range of a digital value can be changed into arbitrary ranges between
-32768 and 32767.
A digital input value stored in CH scaling value (buffer memory addresses Un\G1 to Un\G6) is converted from the range set by CH scaling upper/lower limit value (buffer memory addresses Un\G54
to Un\G65) into the analog output range.
Digital input values which equal analog outputs up to 22 mA are allowed (The limit for the digital
input value is 32767). Outputs greater than 22 mA will result in an error.
For both ranges, digital input values which equal analog outputs down to 0 mA are allowed (The limit
for the digital input value is -32768). Outputs smaller than 0 mA will result in an error.
When the warning function is used (refer to section 3.3.5), input values converted within the scaling
range are checked for warning output.

Warning output function
If the digital input value written to the buffer memory (addresses Un\G1 to Un\G6) is equal to or
greater than the warning output upper limit value or is equal to or less than the warning output lower
limit value, the warning output flag (buffer memory address Un\G48) and warning output signal (XE)
turn ON to give a warning. The warning is triggered for the D/A conversion enabled channel only. For
a description of the warning output upper/lower limit value, please refer to section 3.5.15.
The warning output flag will be set if one of the following conditions is fulfilled:
• Warning output lower limit 욷 digital value
• Warning output upper limit 울 digital value
At occurrence of the warning, the analog output value is converted from the digital value at the warning output upper limit value or warning output lower limit value.
The warning output flag (buffer memory address Un\G48) and warning output signal (XE) turn OFF
when the operating condition setting request (Y9) or warning output clear request (YE) turns ON.
For each channel, the warning output can be enabled or disabled by the disconnection detection/
warning output setting (buffer memory address Un\G47). To enable the warning output, write "0" to
the bit position corresponding to the channel number and turn ON the operating condition setting
request (Y9). As default warning output is disabled for all channels.
Set the warning output upper and lower limit values to the buffer memory addresses Un\G86 to
Un\G97. When the scaling function is used, input values converted within the scaling range are
checked for warning output.

HART Master Function
What is HART?
HART stands for Highway Addressable Remote Transducer.
HART Communication is a bi-directional industrial field communication protocol used to communicate between intelligent field instruments and host systems. A host system can be a handheld device,
a Distributed Control System, Asset Management System, Safety System or a PLC.
There are several reasons to have a host communicate with a field instrument. These include:
– Device Configuration or re-configuration
– Device Diagnostics
– Device Troubleshooting
– Reading the values of additional measurements provided by the device
– Device Health and Status
– And much more!
How HART Works
When using the ME1DA6HAI-Q, HART communication takes place between the analog output module and a HART-enabled field device, for example an actuator for a valve. The ME1DA6HAI-Q can communicate with up to six HART-enabled devices. (One HART device connected to each channel.)
Communication occurs using standard instrumentation grade wire and using standard wiring and
termination practices – no additional wiring is required.
HART provides two simultaneous communication channels: the 4 to 20 mA analog signal and a digital
signal. The 4 to 20 mA signal communicates the analog output value fast, robust and reliable. Additional device information is communicated using a digital signal that is superimposed on the analog
signal. The digital signal contains information from the device including device status, diagnostics,
etc.
The HART protocol makes use of the Bell 202 Frequency Shift Keying (FSK) standard to superimpose
digital communication signals at a low level on top of the 4 to 20 mA analog signal.

A digital signal with a frequency of 2200 Hz is interpreted as logical "0", whereas a frequency of
1200 Hz is interpreted as logical "1".
The HART protocol communicates without interrupting the 4 to 20 mA signal and allows a host appli-

Detailed Description of the Module
cation (in this case the ME1DA6HAI-Q) to get two or more digital updates per second from a field
device. As the digital FSK signal is phase continuous, there is no interference with the analog 4 to
20 mA signal.
HART is a master/slave protocol which means that a field (slave) device only speaks when spoken to
by the ME1DA6HAI-Q (master). This is done by commands send by the ME1DA6HAI-Q. Codes vary by
manufacturer/device.
Examples for commands:
– Set Primary Variable Units
– Set Upper Range
– Set Lower Range
– Set Damping Value
– Set Tag
– Set Date
– Set Descriptor
– Perform Loop Test - Force loop current to specific value
– Initiate Self Test - Start device self test
– Get More Status Available Information
NOTE
The supported commands are depended on the specification of the HART transmitter.
The ME1DA6HAI-Q can operate as a HART master with protocol revision 6.
NOTE
The start up time of the connected HART devices must be considered. If it is long, HART communication errors may occur after switching on the system.
HART Data
The following list is only a brief overview of the data transmitted via the HART protocol. Fore more
information please refer to the description of the buffer memory (Section 3.5.1).
● Digital data: 35 to 40 valuable data items standard in every HART device
● Device identification: device tag, supplier, device type and revision, device serial number
● Calibration data: upper and lower range values, upper and lower sensor limits, PV damping, last
calibration date
● Process variables: primary variable plus secondary measurements and multivariable parameters
● Status/diagnostic alerts: device malfunction, configuration change, power fail restart, loop current fixed or saturated, primary or secondary variable out of limits, communication error etc.
More information
This short overview about the HART protocol is only a extract of the information provided on the website of the HART Communication Foundation. You can find much more information about HART and
answers to frequently asked questions on their website at www.hartcomm2.org.
FDT/DTM function support
Using a commercially available FDT, reading/writing the HART transmitter’s parameters and monitoring the HART transmitter status are executable via the ME1DA6HAI-Q.
Refer to section 4.6 (Setting of the HART Devices) for more details about the FDT/DTM* system
structure.
* FDT stands for Field Device Tool and DTM stands for Device Type Manager. FDT/DTM is a communication technique for
the manufacturer-independent configuration of processing systems at a field bus.

Buffer Memory
Buffer Memory
The HART analog output module has a memory range assigned as a buffer for temporary storage of
data, such as digital values intended for D/A conversion or HART device data. The PLC CPU can access
this buffer and both read the stored values from it and write new values to it which the module can
then process (digital values, settings for the module’s functions etc).
Each buffer memory address consists of 16 bits.
Buffer memory address
Fig. 3-11: Assignments of bits to a buffer memory address
NOTE
Do not write data in the "system areas" of the buffer memory. If data is written to any of the system
areas, the PLC system may not be operated properly. Some of the user areas contain partially system areas. Care must be taken when reading/writing to the buffer memory.
Also, do not write data (e.g. in a sequence program) to the buffer memory area where writing is
disabled. Doing so may cause malfunction.
The "Default" value indicated in the following tables is the initial value set after the power is turned on
or the PLC CPU is reset.
Instructions for data exchange with the buffer memory
Communication between the PLC CPU and the buffer memory of special function modules is performed with FROM and TO instructions.
The buffer memory of a special function module can also accessed directly, e. g. with a MOV instruction. The special function module addressed in this way can be mounted on a base unit or an extension base unit but not in remote I/O stations.
Format of the device address: Un\Gn
– Un: Head address of the special function module
– Gn: Buffer memory address (decimal)
For example the device address U3\G11designates the buffer memory address 11 in the special function module with the head address 3 (X/Y30 to X/Y3F).
In this User's Manual the latter form of addressing is used throughout.
For full documentation of all the instructions with examples please refer to the Programming Manual
for the A/Q series and the MELSEC System Q, art. no. 87431.

HART Analog Output Module ME1DA6HAI-Q

Detailed Description of the Module
3.5.2
Buffer Memory
CH digital value (Un\G1 to Un\G6)
● This area is used by the programmable controller CPU to write digital values for performing D/A
conversion. These values are written as 16-bit signed binary code.

Detailed Description of the Module
CH set value check codes (Un\G11 to Un\G16)
● Digital values set in CH Digital value (Un\G1 to Un\G6) are checked and if any of them is outside
the settable range, the check result is stored in this area.
● When a digital value outside the settable range is written, one of the check codes listed in the
table below is stored.
Description
Check code
000FH
A digital value exceeding the valid range was written.
00F0H
A digital value that falls short of the valid range was written.
00FFH
A digital value that either falls short or exceeds the valid range was written.
For example, the 00FFH check code is stored if a digital value exceeding the valid range was written,
and then, without the check code being reset, a digital value that falls short of the valid range was
written.
Tab. 3-25: Set value check codes
● Once a check code is stored, it will not be reset even if the digital value is within the valid range.
● To reset the CH set value check code, set the error clear request (YF) to ON after rewriting the
digital value so that it is within the valid range.
3.5.4
Error code (Un\G19)
● An error code generated by the D/A converter module is stored in the buffer memory address
Un\G19.

● Set a scaling conversion range for each channel.
● To validate the settings, the operating condition setting request (Y9) must be turned ON/OFF. (Refer
to section 3.4.2)
● The setting range is -32768 to 32767.
For details of the scaling function, refer to section 3.3.4.
NOTES
Setting a value outside the above setting range or a value that does not meet the inequality "Upper
limit > Lower limit" will cause an error. If this occurs, an error code is stored in the buffer memory
address Un\G19, the Error flag (XF) is switched ON, and the module will operate under the setting
before the error.
Since the default setting is 0, changing of the setting is required for operation.
When the Scaling enable/disable setting (Un\G53) is set to "Disable", scaling upper/lower limit values
are ignored.

Wiring precautions
Wiring
In order to optimize the functions of the HART analog output module and ensure system reliability, external
wiring that is protected from noise is required. Please observe the following precautions for external wiring:
● Use separate cables for the AC control circuit and the external output signals of the analog output
module to prevent influences of AC surge or induction.
● Do not lay cables for analog signals close to the main circuit, high-voltage power lines, or load
lines. Otherwise effects of noise or surge induction are likely to take place. Keep a safe distance
of more than 100 mm from the above when wiring.
● The FG terminal of ME1DA6HAI-Q must be connected to the ground certainly.
● The shield wire or the shield of the shielded cable must be grounded at one end.
● Observe the following items for wiring the terminal block. Ignorance of these items may cause
electric shock, short circuit, disconnection, or damage of the product:
– Use solderless terminals for the connection. Twist the end of stranded wires and make sure
there are no loose wires.
– Solderless terminals with insulating sleeves cannot be used for the terminal block. Covering
the cable-connection portion of the solderless terminal with a marked tube or an insulation
tube is recommended.
– Do not solder-plate the electric wire ends.
– Connect only electric wires of regular size.
– Tightening of terminal block screws should follow the torque described on the previous page.
– Fix the electric wires so that the terminal block and connected parts of electric wires are not
directly stressed.
● When wiring to the module placed on the right side of the ME1DA6HAI-Q is difficult, remove the
ME1DA6HAI-Q before wiring.

Setup and Procedures before Operation
External wiring
The ME1DA6HAI-Q is designed for current output only. Devices requiring a current input for instance
as setting value such as actuators, servo amplifiers or inverters can be connected. It is also possible to
mix standard (not HART enabled) devices with HART devices. For HART enabled devices, no additional
wiring is required since the analog output wiring is used for communication between the
ME1DA6HAI-Q and the device (refer to section 3.3.6).
To each output channel of the ME1DA6HAI-Q one HART enabled device can be connected in a pointto-point configuration. Multidrop network connection (more than one device to one channel) is not
possible.
Applicable cables
Concerning to the applicable cable, refer to the HART specification for more details.
External power supply
For operation of the ME1DA6HAI-Q, an external power supply of 24 V DC (+20%, -15%, which gives a
voltage range of 20.4 to 28.8 V DC), is required.

These instructions are optional. If the HART devices are set and monitored with the tool MX CommDTM-HART,
these instructions can be omitted.
The parameters are written to the buffer memory of the ME1DA6HAI-Q.
Several REMTO instructions are used since these parameters are not consecutively in the buffer memory. They
are executed successively because these REMTO instructions use all the same communication channel.
When the last REMTO instruction has been executed, the operation condition setting request is turned ON.
When the setting is completed, the operation condition setting request is turned OFF.
Since the initial setting is completed, the "Perform initial setting" relay is also reset.
