Response Monitor Area (Offset: +0)
The structure of the response monitor area is the same whether SYSWAY or
CompoWay/F communications are used. See Response Monitor Area on
page 248 for details on the response monitor area.
Write Data (Offset: +1, +3, +4, +5, +6, +7, and +8)
Set the words of data to be written to the Temperature Controller as 2's com-
plement signed binary data.
If a communications error occurs while writing data, the remaining write data
will not be written and the next process for the general-purpose communica-
tions device will be executed. The error code will be written to the response
monitor area.
The following example shows the results of the write operation when a com-
munications error occurred while writing the target temperature in command
group 2.
• Response Monitor Area: Contains the error code.
• Target temperature:
• Operation Command:
Note The decimal point position has to be managed by the user since the Tempera-
ture Controller's decimal point position is not transferred in SYSWAY (X for-
mat) communications.
Operation Command (Offset: +2)
Store the operation command code (0000 to 0005) in this word. When a com-
mand group that includes the operation command is selected, the corre-
sponding operation command will be sent to the Temperature Controller.
