BULLETIN 1203-SM1
ENHANCED MODE
APPLICATION NOTE# SM1 - 2
May 27, 1997
PURPOSE
The purpose of this document is to provide guidelines for wiring and control
schemes for SCANport devices including Bulletin 1305 and 1336 PLUS AC
Drives. This document is a suggestion only. Users must ensure that installations
meet applicable codes and are suitable for the existing conditions.
WHAT THIS NOTE
CONTAINS
This document contains information and an example ladder program that
demonstrate how to control three 1305 drives using an SLC-5/03 and a 1203SM1 module. This note uses the 1203-SM1 configured as an enhanced mode
module. The 1203-SM1 can be used with an SLC 5/02, 5/03, or 5/04 processor
in this configuration.
INTENDED
AUDIENCE
This application note should be used by personnel familiar with the hardware
components and programming procedures necessary to operate SCANport
devices. It is also assumed that the user has some familiarity with the SLC-500
and ladder programming.
WHERE IT
IS USED
The diagrams, parameter settings and auxiliary hardware used in this application
note are designed to address specific issues in many different applications.
Some changes by the user may be necessary to apply the concepts of this
document to a specific application.
APPLICATION
CONSIDERATIONS
These example ladder programs were written to be simple and clear examples.
Consult the SLC and 1203-SM1 manuals for more information.
When used as an enhanced mode module, the 1203-SM1 extends the model
used by the basic mode configuration. The enhanced mode configuration adds:
•
Datalinks
•
Safe State Data
•
Messaging
If these functions are not required OR to aid in understanding the differences
between the two configurations refer to the application note “Bulletin 1203-SM1
Basic Mode”.

This application note does not explain messaging. For more information on
messaging refer to the application note “Bulletin 1203-SM1 SCANport
Messaging”.
SCANport devices may assign different meanings to bits in the Logic Command
and Status words. The usage of the Reference and Feedback words may also
vary. Consult the manual for your SCANport device for more information.
SLC
CONFIGURATION
The screen prints in Figures 1 and 2 show the configuration of the SLC system
for the example program. Figure 3 explains how the “G” file is used in the 1203SM1 module.
As is shown in Figure 1, the SLC rack is configured with a 1203-SM1 module
installed in the first slot. A 1747-IA16 module is installed in slot 2 and a 1747OV8 module is installed in slot 3. The module ID code for the 1203-SM1 is 13616
when used as an enhanced mode module.

Figure 2 -- 1203-SM1 Configuration
Figure 3 shows the configuration of the ‘G’ file for the 1203-SM1 module. The
first word is set by APS and should not be modified. Each bit in the second word
enables a Datalink. Refer to the manual for your SCANport device for more
information about Datalinks.
Each remaining word in the ‘G’ file contains Safe State Data. This is the data that
will be sent to the attached SCANport device(s) if the 1203-SM1 dip switch is
configured to use Safe State Data and the SLC becomes faulted or is changed to
program mode.

DATALINKS
A Datalink is a type of pointer used by some SCANport devices to transfer
information between the SLC and the device. Datalinks allow a parameter value
to be changed without using the 1203-SM1 messaging function.
SCANport devices that support this function have a group of parameters for
Datalink configuration. These parameters are identified as “Data In” and “Data
Out” parameters. Datalinks are enabled by bits in the first word of the 1203-SM1
“G” file (refer to the section on “G” file configuration).
Each Datalink provides two words of input and two words of output when enabled.
A simple Datalink application is to set a parameter number into one of the “Data
In” parameters. The SLC output image word for that Datalink will then control the
value of that parameter.
For example: On a 1336 PLUS drive connected to channel 1 of a 1203-SM1
module installed in slot 1 use Datalink A1 to control the value of Parameter 27.
First, set the lowest bit of the second word of the “G” file to a 1 (enables Datalink
A on channel 1). Use a HIM to set parameter 111 (Data In A1) to “27”. The value
in O:1.8 will now control the value of parameter 27 in the 1336 PLUS drive.
A similar Datalink application is to set a parameter number into one of the “Data
Out” parameters. The value of that parameter will then appear in the SLC input
image word for that parameter.
For example: On a 1336 PLUS drive connected to channel 1 of a 1203-SM1
module installed in slot 1 use Datalink A1 to monitor the value of Parameter 27.
First, set the lowest bit of the second word of the “G” file to a 1 (enables Datalink
A on channel 1). Use a HIM to set parameter 119 (Data In A1) to “27”. The value
in I:1.8 will now monitor the value of parameter 27 in the 1336 PLUS drive.

Channel 3 Status
NOTE: x = Designated SCANport Channel Number on the module.
IDx
SCANport Channel x Connected Adapter Port ID Number. This three (3) bit field
contains the adapter port number that channel x is connected to on the SCANport
product. It should contain a value between 1-7. If this field contains a seven (7),
then the channel is not connected to the SCANport product, or the SCANport
product may not be powered.
Vx
SCANport Channel x Valid Data bit. When high (1), the Logic Status and Analog
Feedback values are valid and can be used. When low (0), the values should not
be considered valid.
A-Dx
SCANport Channel x Datalink A-D Valid Data bit. When high (1) the data
associated Datalink A-D of the corresponding channel is valid and can be used.
When low (0) the values should not be considered valid.
M0 STAT
M0-File Status bit. When high (1), any previously written M0-file message to the
module can be enabled by the SLC program. When low (0), the SLC to SCANport
module is either actively reading the last sent M0_file data changes, or no M0_file
data has been loaded into the module by the SLC program. Under SLC program
control, any changes to the M0-file message buffers should cause the checking
of this status bit before enabling that message to be sent out any SCANport
channel. Unchanged buffers can still be enabled or sent while this status bit is low
(0).
MSTAT CHx
Message Status bits for the message buffer of the corresponding channel. These
two (2) bit fields correspond to the status of each of the message buffers. There
is one message response buffer for each channel. The first bit (MSB) contains
the READY bit. The READY bit is active (high=1) when a new message request
can be initiated to the SCANport product. The second bit (LSB) contains the
DONE bit. The DONE bit is active (high=1) when an M1-file message buffer
contains response data to a message request. When both the READY and the
DONE bits are inactive (0), the buffer is in a BUSY state. This is the state during
which the module is actually requesting the data from the SCANport product.
These status bits should never be high at the same time.
NOTE:
The 1203-SM1 can be used to read and write parameters and other information
in a SCANport device. For more information refer to the application note “Bulletin
1203-SM1 SCANport Messaging”.

Channel 3 Command
NOTE: x = Designated SCANport Channel Number on the module.
DEx
SCANport Channel x Data Enable bit. While low (0), the Channel will not be
actively transferring I/O data (including datalink data) between the connected
SCANport product. When high (1), the Channel will become active to the
SCANport product and transfer the appropriate I/O data. When reset to low (0),
the Channel will disconnect from the SCANport product. NOTE: This will usually
cause the connected SCANport product to fault.
MEx
SCANport Channel x Message Enable bit. When set high (1), the message
selected by the Message ID field will be transmitted through the appropriate
channel to the SCANport product. This bit should be held high during the duration
of the request until the status DONE bit is asserted (1). The resetting (0) of this bit
clears the DONE status, and returns the message status to the READY state.
MSG ID
Message Identifier field. This field allows for the selection of one of the eight (8)
message buffers in the M0-file area for each channel. Multiple channels can
utilize the same Message ID buffer simultaneously.
NOTE:
The 1203-SM1 can be used to read and write parameters and other information
in a SCANport device. For more information refer to the application note “Bulletin
1203-SM1 SCANport Messaging”.
