[ d ] Ch-No (Communication Buffer Channel)
Specifies the channel number of the communication buffer.
The communication buffer channel number is the buffer number to be used for the data exchange between the CPU
Module and the Ethernet Module. (It is not the connection number in the connection parameters of the module detailed
definition.)
When executing more than one function simultaneously, do not duplicate a channel number within the same circuit.
(The channel number can be duplicated if functions are not executed simultaneously.)
The table below shows the valid range of channel numbers.
Transmission Device
Built-in Ethernet Module
218IF-02 Module
218IF-01 Module
When the built-in Ethernet Module is used as the transmission device, simultaneous transmission or reception of
IMPORTANT up to four circuits is possible by using channel numbers 1 to 4 because this provides four channels of
communication buffers common to data transmission and reception.
