1.2 Impulse counter modes

The instrument allows for 5 selectable impulse counter modes :

• Counter (‘cn.1’)


• Counter quadrature (‘cnq.2’) (see section 1.19.3)

• Counter with inhibition (‘ cnI.3

’)


• Counter with control add / substract (‘ cnc.4

’) (see section 1.19.5)

• Counter differential (‘cnd.5’)


Configurable up or down counting, ‘reset’ at rear terminals, front key and/or at alarm activation. Configurable ‘Preset’ value. Relay activa tion and deactivation delays.

Alarm functions with ‘return to preset’ or ‘reset to 0’ generate cycles of counting (instrument counts from ‘preset’ value to alarm value in never ending cycle). The instrument provides memory of cycles counter.

Scalable reading with configurable multiplier factor (1 to 999999) and configurable divider factor (1 to 999999). Memory retention in case or power loss. Retains configuration and last reading.

Counting frequency up to 250 KHz, in ‘FAST’ mode (see section 1.16)

.

1.3 Ratemeter modes

In ratemeter mode the reading is proportional to the measured fre quency. The instrument allows for 2 selectable ratemeter modes :

• Ratemeter (‘rt.6’) (see section 1.19.7)

• Ratemeter quadrature (‘rtq.7’)


The ratemeter mode has a single input channel, with scalable read ing. The quadrature ratemeter mode has 2 inpur channels available for detection of sense of turn when working with quadrature signals.

Scalable reading with configurable multiplier factor (1 to 999999) and configurable divider factor (1 to 999999).

For low frequency applications, the ‘SLOW’ mode provides the best response time for each application

(see section 1.15) .

Maximum frequency up to 500 KHz and minimum frequency down to de 0.001 Hz (1 mHz) with ‘SLOW’ mode active.

1.13 Function ‘Trigger Sense’

The trigger level is automatically configured when selecting a sensor from the ‘Sensor / Configuration’ (‘SnSr’ / ‘Auto’) menu list. The trig ger level can be also manually modified from the ‘SnSr’ / ‘ TrIG ’ menu entry. The selected value applies to channels ‘A’ and ‘B’ (the reset has a fixed trigger level at 2.5 Vdc).

At the ‘SnSr’ / ‘ TrIG ’ menu, the instrument shows the trigger level and two vertical leds to the left. These leds inform in real time about the status (‘0’ or ‘1’) of the input channels ‘A’ and ‘B’. When the led switches between up and down position, it indicates that impulses are being detected at the input. If the instrument does not detect impulses, the led positions remain fixed.

Increase the trigger level pressing key ‘UP’ ( 5 ) and decrease press ing key ‘LE’ ( 3 ).

1.14 Function ‘cycle counter’

The counter modes allow to activate a reset function (to ‘0’ or to

‘preset’ value) when an alarm setpoint is reached. With this configu ration, the instrument counts in cycles, counting from the instrument preset value up to the alarm setpoint. Each cycle is counted and ac cumulated into an internal memory, accessible through the ‘fast ac cess’ menu (key UP ( 5

) (see section 1.19.12))

.

To reset the memory of cycles, visualize the value at the ‘uP’ menu, then press the ( 5 ) key and the ‘rSt’ message appears. Press ( < ) to reset.

1.15 ‘SLOW’ mode

Special working mode for applications with low frequency signals.

Applies to ratemeter (‘rt.6’), ratemeter quadrature (‘rtq.7’) and peri odmeter (‘Prd.8’). The ‘SLOW’ mode allows to measure slow fre quencies down to 1 mHz (0,001 Hz) and is functional up to 200 Hz.

The ‘SLOW’ mode provides the fastest response time possible for a given application, calculating the frequency and the period based on the time between consecutive impulses.

The ‘SLOW’ mode needs to define the parameter ‘ maximum waiting time ’ to a value between 1 and 1000 seconds. If this time expires without a single impulse being received, the reading jumps to ‘0’

(both for ratemeter and periodmeter modes). The ‘GATE’ parameter is not used if ‘SLOW’ mode is active.

In ‘ratemeter quadrature’ (‘rtq.7’) mode, the activation of the

‘ SLOW’ mode calculates the frequency based on the time between consecutive impulses received on channel A, and calculates the sense of turn (clockwise or counter-clockwise) by comparing each impulse with the state of channel B. The ‘edge’ parameter is fixed to a ‘ 1--1’. Typical application for quadrature frequency measure with two inductive sensors at low frequency.

1.16 ‘FAST’ mode

Special working mode for counter applications with high frequency signals, up to 250 KHz. Applies only to the counter mode (‘cn.1’).

The activation of the ‘FAST’ mode configures the signal detection by rising edge. The first edge detected, either rising or falling edge, after the instrument restart (power-up, or configuration change) is used for internal initialization and will not be counted as impulse.

1.17 How to operate the menus

The instrument has two menus accessible to the user :

‘ Configuration menu ’ (key SQ) ( < )

‘ Fast access ’ menu (key UP) ( 5 )

Configuration menu

The ‘ configuration menu ’ modifies the configuration parameters to adapt the instrument to the application needs. To access the ‘ con figuration menu ’ press for 1 second the SQ ( < ) key. This access can be blocked by activating the ‘Password’ (‘PASS’) function. While operating the ‘ configuration menu ’, the alarm status is ‘hold’ to the status they had before accessing the menu, and the output and con trol modules remain in ‘ error ’ state. When leaving the ‘ configuration menu ’, the instrument applies a system reset, followed by a brief disconnection of the alarms and the output and control modules.

Functionality is then recovered.

For a detailed explanation on the ‘ configuration menu ’ see section

1.19

, and for a full view of the ‘

configuration menu ’ structure see

section 1.20

.

‘ Fast access ’ menu

The ‘ fast access ’ menu is an operator configurable menu, providing fast and direct access to the most usual functions of the instrument with a single key pad stroke. Press key UP ( 5 ) to access this menu.

See section

1.19.12

for a list of functions eligible for ‘

fast access ’ in this instrument. The ‘Password’ (‘PASS’) function does not block ac cess to this menu. Accessing and modifying parameters in the ‘ fast access ’ menu does not interfere with the normal functionality of the instrument, and it does not generate any system reset when validat ing the changes.

Front key pad description

Key SQ ( < ) - press the SQ ( < ) key for 1 second to access the ‘ con figuration menu ’. Inside the menu, the SQ ( < ) key functions as a

‘ENTER’ key. It selects and accesses the menu option currently dis played. At menus with numerical value entries, it validates the num ber displayed.

Key UP ( 5 ) - the UP ( 5 ) key gives access to the ‘fast access’ menu.

Inside the menus, it moves vertically through the different menu op tions. At menus with numerical value entries, it modifies the digit selected by increasing its value to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

Key LE ( 3 ) - inside the menus, the LE ( 3 ) key functions as the ‘ ES-

CAPE ’ key. It leaves the selected menu, and eventually, will leave the whole menu. When leaving the ‘ configuration menu ’ with the LE ( 3 ) key, the changed parameters are activated. At menus with numeri cal value entries, the LE ( 3 ) key allows to select the active digit. To modify the value of the selected digit use the UP ( 5 ) key.

Menu ‘rollback’

After 30 seconds without interaction from the operator, the instru ment will rollback and leave the ‘ configuration menu ’ or the ‘ fast access ’ menu. All changes will be discarded.

• ‘ Pulls on channel A’ (‘PuL.A’) - activates pull resistors at chan nel A. Select ‘P.uP’ to activate pull-up resistors (needed for NPN sensors). Select ‘P.dn’ to activate pull-down resistors (needed PNP sensors). Pull-up and pull-down selection configure the trigger level to 2,5 Vdc.

• ‘ Pulls on channel B’ (‘ PuL.b

’) - see previous menu entry ‘Pulls on channel A’.

• ‘ Pulls on reset’ (‘PuL.r’) - see previous menu entry ‘Pulls on channel

A’. Trigger level for reset channel is fixed to 2,5 Vdc.

• ‘ trigger level’ (‘ trIG ’) - input signal value in Vdc at which the in strument detects impulse. Selectable between 0,0 and 3,9 Vdc. Trig ger level is the same for channels A and B. Trigger level for reset channel is fixed at 2,5 Vdc. The two leds at the left of the trigger level are part of the ‘Trigger Sense’ utility for easy location of the

proper trigger level (see section 1.13) .

• ‘ Activation for channel A ’ (‘Act.A’) - configures the activation of channel A by rising edge (‘on_h’) or by falling edge (‘on_0’)

• ‘ Activation for reset channel ’ (‘Act.r’) - configures the activa tion of the reset channel by rising edge (‘on_h’) or by falling edge

(‘on_0’)

• ‘ Excitation voltage ’ (‘ V.EXc

’) - configures the value of the excita tion voltage at 5 Vdc, 9 Vdc, 15 Vdc and 18 Vdc. Select ‘no’ to disable the excitation voltage.

• ‘ Antirrebound filter ’ (‘ rbnd ’) - the antirrebound filter blocks ad ditional rebounds (typically from a mechanical contact sensor) from the same single impulse, preventing that a single impulse counts for more than 1. Value between 0 mSeconds and 1000 mSeconds.

When an impulse is received, impulse detection is disabled for the duration of the time configured in this parameter. After time has passed, impulse detection is enabled again. Recommended value for a mechanical contact : 100 mSeconds.

1.19.11 Alarms

The ‘Alarms’ (‘ALr’) menu configures the independent activation of up to 3 relay outputs (or transistor or SSR drive control), installed with the R1 optional modules (or T1 or SSR)

(see section 2.1) . For

outputs up to 4 and 6 relays, see special modules R2, R4 and R6 at section

2.6

. The alarm states are indicated in the front display with

leds marked as ‘1’, ‘2’ and ‘3’.

To configure an alarm, enter into the alarm menu (‘ALr1’, ‘ALr2 ’ or

‘ ALr3 ’) and configure the following parameters :

• select ‘ Active ’ (‘Act’) to ‘on ’

• at ‘ Alarm type’ (‘TypE’) select the alarm to act as a maximum type alarm (‘MAX’) or a minimum type alarm (‘ MIn ’). The maximum type alarm (or minimum type alarm) activates when the display value is higher (or lower) than the setpoint value.

• at ‘ Setpoint’ (‘SEt’) enter the value for the alarm activation point .

This parameter is eligible for configuration through the ‘ Fast access ’ menu

(see section 1.19.12).

• configure the hysteresis value at ‘Hysteresis’ (‘hySt’). The hyster esis applies to the deactivation process of the alarm. The alarm de activates when the reading has passed the setpoint value plus the hysteresis value. Hysteresis helps to avoid repetitive switching of the alarm relays, due to fluctuating input signals around the setpoint.

• at ‘ Activation delay ’ (‘dEL.0’) configure the delay to apply before alarm activation. The activation delay starts counting when the set point value is passed. Value from 0.0 to 99.9 seconds.

• at ‘ Deactivation delay ’ (‘dEL.1’) configure the delay to apply before alarm deactivation. The deactivation delay starts counting when the setpoint value plus the hysteresis value, is passed. Value from 0.0 to 99.9 seconds.

• to work with ‘windowed alarms’ (see graphical example below) activate ‘Setpoint 2’ (‘SEt2’) to ‘on’ and then configure the desired second setpoint value. Second setpoint must always be higher in value than the first setpoint.

• the ‘Relay inverted’ (‘ r.Inv

’) parameter inverts the normal relay connections. When set to ‘on’ the relay will be active when alarm is inactive. For security applications where an inactive relay controls the shutdown of the system.

• the ‘Locked alarm’ (‘A.Lck’) parameter disables the automatic deactivation of the alarm. Alarm deactivation must be performed

manually, by pressing the ‘LE’ front button (see section 1.19.14)

• the ‘On alarm’ (‘on.AL’) parameter assigns a predefined behav iour when alarm is activated. Select ‘cont’ to continue counting.

Select ‘to_0’ to load ‘0’ on displays. Select ‘to_p’ to load preset value on display. Parameter ‘dEL.1’ is set to 1 second when ‘to_0 ’ or ‘ to_p’ are selected.

2. Output and control modules

2.1 Módules R1, T1 and SSR

The R1, T1 and SSR modules provides 1 relay output, 1 transistor out put or 1 SSR drive output, to install in DPF20 digital panel meters, up to a maximum of 3 modules in a single meter.

Note : for more than three relays per instrument or larger relay den sity per module, see special modules R2, R4 and R6 .

Configuration is performed from the frontal keypad of the meter, by setting the parameters at the alarms configuration menu (‘ALr.1’,

‘ALr.2’ or ‘ALr.3’ depending on the position the module is installed).

The menu allows to configure the setpoint, hysteresis, independent activation and deactivation delays, and a second setpoint to create alarm windows.

Modules R1, T1 and SSR are isolated against all other instrument cir cuits, and isolated between them.

Modules R1, T1 and SSR can be ordered pre-installed into a DPF20 digital panel meter, or standalone for delayed installation, as they do not require soldering or special configuration.

Exception codes

The Modbus RTU protocol defines the following scenarios when a

‘Master’ is sending a frame to a ‘Slave’:

• the ‘Slave’ device receives the frame correctly and replies with the requested data

• the ‘Slave’ devices detects a CRC error, parity error, or other. and discards the frame without generating a reply frame. The ‘Master’ will detect a ‘TIMEOUT’ condition due to the absence of reply.

• the ‘Slave’ device receives the frame correctly, but replies with an

‘EXCEPTION_CODE’ as it can not process the function or register re quested.

The ‘EXCEPTION_CODES’ configured in the RTU module are :

At menu ‘ Configuration ASCII ’ (‘ AScI ’), configure the instrument at parameter ‘Mode’ (‘ModE’) to work as ‘slave’ or ‘master’, at param eter ‘ Address’ (‘Addr’) set the address value from ‘1’ to ‘31’, set the bus speed in kbps at parameter ‘Speed’ (‘ bAud ’) and set the data format at parameter ‘Format’ (‘ bItS ’).

When working as ‘master’, the instrument continuously transmits the display value data frame. The local module address is ‘0’. Con figure at menu ‘ Configuration Master ’ (‘cnF.M’) the ‘ Destination ad -

dress’ (‘d.Add’) parameter from ‘1’ to ‘31’ or use value ‘128’ for a broadcast message. At parameter ‘Frequency’ (‘FrEq’) select the how often the frame with the reading value will be transmitted.

Special tools are grouped inside the ‘Tools’ (‘TooL’) menu.

• the ‘Decimal point’ (‘dP’) menu is provided for compatibility with ancient hardware that does not support decimal point retransmis sion. By default, select ‘ Automatic ’ (‘Auto’). If your instrument does nos transmit the decimal point position, select ‘Manual ’

(‘MAnL’) and fix the position of the decimal point manually.

•the ‘Legacy mode’ (‘ LEG’ ) parameter is provided to maintain compatibility with instruments with older communication proto cols. Select ‘on’ to activate this mode.

• the ‘Answer delay’ (‘ AnS.d’ ) parameter applies only to ‘Slave’ mode. The local module delays the answer frame. Configure for applications where the ‘Master’ needs additional time to switch between ‘transmit’ and ‘receive’ modes. Enter a numeric value be tween ‘0’ and ‘1000’ mSeconds.

• at the ‘Factory reset’ (‘FAct’) menu, select ‘yes’ to load the de fault factory configuration for the instrument.

the ‘ Version ’ (‘ VEr ’) menu informs of the current firmware version installed in the module.

Frame types

The ASCII protocol defines the following frames:

• Frame ‘read’ (‘RD’). Id code 36. Request data frame. The requested register is indicated into the ‘REG’ byte (‘Header’ section).

• Frame ‘answer’ (‘ ANS ’). Id code 37. Response frame to a request data frame. The requested register is indicated into the ‘REG’ byte’

(‘Header’ section). Data of the requested register is indicated into data bytes ‘D0’ to ‘Dn’ (‘Data’ section).

2.4.5 Frame structure

• Frame ‘error’ (‘ERR’). Id code 38. Response frame to a request data frame. Indicates that an error has occurred. Error code is codified into the ‘REG’ byte (‘Header’ section).

• Frame ‘ping’ (‘ PING ’). Id code 32. Used to confirm the existence of the remote instrument.

• Frame ‘pong’ (‘ PONG ’). Id code 33. Response to a ‘ping’ frame. It confirms the existence of the remote instrument.

Protocol frames have a structure made of ‘Header’, ‘Data’ and ‘Trail’.

Section ‘Header’

Contains the start byte (‘STX’), the frame identifier (‘ID’), the origin address (‘FROM’) and the destination address (‘TO’), the register id

(‘REG’) and the length (‘LONG’) of the ‘Data’ section.

Section ‘Data’

Contains data for the requested register (‘REG’).

Section ‘Trail’

Contains the ‘CRC’ code and the end of frame byte (‘ETX’).

‘Real value’ and ‘Frame value’

To use representable ASCII values, the real values are codified before being sent into the frame. The following definitions apply :

• ‘real value’ is the value of the field without codification

• ‘frame value’ is the value of the field, codified

2.4.8 CRC calculation

The ‘frame value’ for the CRC byte is calculated applying a XOR func tion to the ‘frame value’

(see section 2.4.5) of all bytes in sections

‘Header’ and ‘Data’, from byte ‘0’ (‘STX’) to the last data byte (‘Dn’).

• if the calculated CRC value is lower than ‘32’, it is normalized by ap plying the ‘one’s complement’ function .

CRC0=STX ^ ID ^ RSV ^ FROM ^ TO ^ REG ^ RSV ^ LONG ^ D0 ^...^ Dn

• if (CRC0<32) -> CRC=!CRC0 (one’s complement function)

• if (CRC0>31) -> CRC=CRC0

//example of CRC calculation in C language

{ int8 Calculate_CRC(int8 CRC_Position)

int8 i,CRC=0;

for(i=0;c<CRC_Position;c++)

{

crc=crc ^ frame[i];

}

}

if(crc<32) CRC=~CRC;

return(CRC);

2.5 Module S2

Module S2 provides 1 RS-232 ASCII communications port, to install in

DPF20 digital panel meters. Protocol specifications are the same as with module S4

(see section 2.4) , with only difference that the physical bus is

RS-232 instead of RS-485.

S2 modules allow for point-to-point communication over RS-232 and also allow for multinode communication over RS-232 using a ‘Daisy-Chain’ type of connection.

Terminals RX1 and TX1 are for connection to the RS-232 bus. Terminals

RX2 and TX2 are for RS-232 multinode connection. Frames received on

RX1 with destination address different than the local instrument’s ad dress, will be retransmitted over the TX2 terminal. In a similar way, frames received from RX2 with destination address other than the local address, will be retransmitted over TX1 terminal.

Up to a maximum of 3 S4 modules can be installed in a single instrument, all modules isolated between them and isolated from all other circuits.

Modules S2 can be ordered pre-installed into a DPF20 digital panel meter, or standalone for delayed installation, as they do not require soldering or special configuration.

2.6 Modules R2, R4 and R6

Modules R2, R4 and R6 provide 2, 4 and 6 relay outputs, to install in

DPF20 digital panel meters.

Configuration is performed from the frontal keypad of the meter, by setting the parameters at the ‘Opt.1’ configuration menu (not from the alarm configuration menu (‘ALr.1’, ‘ALr.2’ o ‘ALr.3’) of the instru ment).

The menu allows to configure the setpoint, hysteresis, independent activation and deactivation delays, and a second setpoint to create alarm windows.

Only 1 modules R2, R4 or R6 can be installed in a single instrument, as the are not compatible with themselves (2 modules R2 are not ac cepted) and are not compatible with modules R1, T1 or SSR.

Modules R2, R4 and R6 are isolated against all other instrument cir cuits.

Modules R2, R4 and R6 can be ordered pre-installed into a DPF20 digital panel meter, or standalone for delayed installation, as they do not require soldering or special configuration.

To configure alarm 1, access the ‘Alarm 1’ (‘ALr1’) menu and config ure the following parameters : To configure alarms 2, 3, etc, access the corresponding menu entries.

• select ‘ Active ’ (‘Act’) to ‘on ’

• at ‘ Alarm type’ (‘TypE’) select the maximum alarm (‘MAX’) or minimum alarm (‘ MIn ’). The maximum alarm (or type alarm) ac tivates when display value is higher (or lower) than the setpoint value.

• at ‘ Setpoint’ (‘SEt’) enter the alarm activation value.

• configure the hysteresis value at ‘Hysteresis’ (‘hySt’). The hyster esis applies to the deactivation process of the alarm. The alarm de activates when the reading has passed the setpoint value plus the hysteresis value.

• at ‘ Delay 0’ (‘dEL.0’) assign the delay to be applied before alarm activation. The activation delay starts counting when the setpoint value is passed. Configurable from 0.0 to 99.9 seconds.

• at ‘ Delay 1’ (‘dEL.1’) assign the delay to be applied before alarm deactivation. The deactivation delay starts counting when the set point value plus the hysteresis value, is passed. Configurable from

0.0 to 99.9 seconds.

• to activate the second setpoint, activate ‘Setpoint 2’ (‘SEt2’) to

‘ on’ and then configure the desired setpoint value. Second setpoint allows for windowed alarms. The first setpoint activates the alarm, and the second setpoint deactivates the alarm (configuration for

‘Alarm as maximum’ type of alarm). Second setpoint must always be higher in value than the first setpoint.
