Working on a PLC configuration with 8 PLC's connected thru ethernet. One PLC is master the other are slaves and must have the commands from the master. Found two options to do this:
1) PLC variable with an array to send to all slaves. Each slave has his own part of the array to put the actual status and to get the command.
Advantage: the time period to get all info directly to all slaves
2) PLC variable without array to send one command from master to one slave and after receiving the confirmation the second command to the next slave.
What is the best option to use?
