This rung times the write message instruction for errors or lockup conditions. The timer restarts communications
whenever an error occurs. Lockup conditions are situations that may arise if the communications path is corrupted. For
example, power is lost at the destination device or a cable is cut. Error conditions are typically caused from noise on the
communications link or a faulty device on the network.
