7. INITIAL COMMUNICATION DATA SETTINGS
IMR02E20-E1
29
Number of setting data items (OUT)
Set the number of communication items used for setting in PROFINET.
Up to 50 communication items can be set.
Among the communication items set in the “Communication data items setting” set the quantity of
the data to be used to the CH number or the Modbus register address corresponding to the
communication items set in the “Number of setting data items (OUT).”
“Number of setting data items (OUT)” (50 items) correspond to CH1 to CH50 of identifier QI of
RKC communication and to Modbus register addresses 8084H to 80B5H.
The data is valid if the total of the values set in “Number of setting data items (OUT)”, a cumulative
value from CH1 or 8084H, is 127 (007FH) or lower. Any data after that are disregarded.
Regardless of the setting of “Number of setting data items (OUT),” “Setting state selection” is
assigned to the first-word of the setting data item (OUT).
For setting configuration, refer to
Setting example (P. 29)
.
Data setting of each items
Set the data of the items set in
“Communication data items setting.”
The content of these items can be set by host communication or loader communication.
Set the data for the communication items corresponding to the Modbus register addresses set in
“Communication data items setting.”
[Example]
Setting the data of CH1 to “100” when “Set value (SV)” is specified in the communication item setting
RKC communication:
Write “100” to CH1 of the RKC communication identifier “S1” of the Set value (SV).
Modbus: Write “100” to the Modbus register address “0ADCH” of CH1 of the Set value (SV).
For setting configuration, refer to
Setting example (P. 29)
.
Setting example
If one Z-TIO module is joined to the COM-ML, set the following conditions:
Use CH1 to CH4 of “Measured value (PV)” and “Set value (SV)” of the Z-TIO module.
Setting condition: Measured data items (IN): Measured value (PV), Set value (SV)
Setting data items (OUT): Set value (SV)
Assigned destination of communication item:
Measured value (PV): CH1 or 8020H
Set value (SV):
CH2 or 8021H
Set value (SV):
CH1: 150, CH2: 200, CH3: 250, CH4: 300
