Argument Specification - Mitsubishi Electric MELSEC iQ-R Series Manual

Argument specification

This section shows the argument specification of the MELSEC iQ-R series data link functions.
Channel
A channel implies a network and communication route to be used when communicating with a C intelligent function module.
A channel number is set for each module in a user program.
A channel to be used for MELSEC iQ-R series data link functions is as follows:
Channel Network
number
12 Bus interface
CPU number, network number, start I/O number, station number
CPU numbers, Network numbers, start I/O numbers and station numbers to be specified to MELSEC iQ-R series data link
functions are as follows:
Access route
Bus interface
CC-Link IE Controller Network
CC-Link IE Field Network
MELSECNET/H network
CC-Link
*1 No error will occur even if the value is set.
*2 A specified control station of the network, which is specified to the network number, is accessed. To access a station that is actually
operating as the control station, specify the station number.
Device type
The following table shows the device types specified to the MELSEC iQ-R series data link functions.
Devices are defined in the header file (MDRFunc.h).
Either a code or a device name can be specified as a device type.
