 Cir-No (Circuit Number)
Specify the circuit number for the communications device.
Specify the same circuit number as displayed on the MPE720 Module Configuration Definition Tab Page.
The following table gives the valid circuit numbers.
 Ch-No (Communications Buffer Channel Number)
Specify the channel number of the communications buffer.
You can specify any channel number provided it is within the valid range.
The following table gives the valid channel numbers.
If the communications device is the 218IFD, there are 10 channels of communications buffers available
for both transmission and reception. Therefore, 10 connections can be used for sending and receiving at
the same time by using channels 1 to 10.
Communications Device Valid Circuit Numbers
218IFD 1 to 8
When executing more than one function simultaneously, do not use the same channel number within
the same connection. You can use the same channel number as long as multiple functions are not exe-
cuted at the same time.
Communications Device Valid Channel Numbers
218IFD 1 to 10
There must be as many MSG-RCVE or MSG-SNDE functions as the number of connections used at
the same time.
