Appendix 9.3 Transient transmission
To perform the transient transmission, it is necessary to provide an interlock as shown
below.
One network module has 8 channels for executing instructions.
Although these channels can be used at the same time, the same channel cannot be
concurrently used for multiple instructions.
If execution of multiple instructions is attempted at the same time on the same channel,
those to be executed later have to wait. For this reason, create a program so that a flag
turns on until the previous instruction is completed, as shown below.
(Example) When executing the same channel with two instructions
