2.10 Communications with a JTEKT PLC (TOYOPUC Protocol)
Message Functions
2-305
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 may be used for sending and receiving at
the same time by using channels 1 to 10.
Param (First Address of Parameter List)
Specify the first address of the parameter list.
A total of 52 words starting from the specified first word are automatically used for the parameter list. The
parameter list is used by inputting the connection number and relevant parameter data. It is also where the
process results and status are output.
When executing more than one function at the same time, do not use the same channel number for the
same connection. You can use the same channel number as long as multiple functions are not executed
at the same time.
Communications Device Valid Channel Numbers
218IFD 1 to 10
There must be as many MSG-SNDE or MSG-RCVE functions as the number of connections used at
the same time.
