Here is a detail to remember: the older TI530 PLC does not work in low-latency mode. It must be set to throughput mode. Its serial driver has a very tight "gap" timeout such that the entire message MUST show up in one continuous stream. In low-latency mode the many small ''''chunks'''' of message may have small gaps at times, which may cause the device to timeout.
