Messaging Functions
The MMI-40 can store a large number of messages. Message numbers can range from 1 to 65500. A register called the Message Triggering Register (MTR) is defined in the PLC. The MMI-40 reads the contents of this register in every scan and the message corresponding to the number in the MTR is displayed on the MMI-40. A message can be assigned to each line on the MMI-40. Messages can scroll, flash, have minimum time for display and can be chained to other messages. They can also be designated to be printed through the serial port.
