➀ This only includes the amount of time needed to set up the operation requested. It does not include the time it takes to service the actual communication, as this time
varies with each network configuration. As an example, 144ms is the actual communication service time for the following configuration: 3 nodes on DH-485
(2=MicroLogix 1000 programmable controllers and 1=PLC-500 A.I. Series programming software), running at 19.2K baud, with 2 words per transfer.
➁ Add 7.3 µseconds per word for MSG instructions that perform writes.
