Program Example Of Cyclic Transmission; Program Example Of Transient Transmission - Mitsubishi Electric MELSEC Q Series Reference Manual

8.2.3

Program example of cyclic transmission

The program example of cyclic transmission of multi-network system is the same as the program example of single
network system. (
8.2.4

Program example of transient transmission

The program example of transient transmission of multi-network system is the same as the program example of single
network system. (
However, when transient transmission is performed to another network, the program example is different from that of
the single network system in the following matter.
Using the following system configuration as an example, the following shows the differences with a program example
of a single network system.

(1) Target station network No. and target station No. of link dedicated instruction
Set the network No. and station No. of request target to the target station network No. ((S1)+4) and target station
No. ((S1+5) specified by the control data. (
(2) Interlock
When executing a link dedicated instruction, establish an interlock with the baton pass status (SW00A0.1) of the
relay station (1N
(3) Routing parameters
Set the routing parameters. (
