As given in this question and the most up-voted answer, it's suggested that PLC-related questions may be on-topic. However, upon reading the tour, it points out this meta question, which indicates that only consumer-computer related systems are on-topic.
I have a question specifically regarding a motor to perform a specific function, that must be able to be driven from a PLC (even if it's as simple as a "move forward" or "move backward" signal), but I'm very seriously confused as to whether it fits here or not.
So, is a question regarding a PLC peripheral on-topic? Not a PLC itself, but a device that would be controlled through the PLC.
