Chapter 9 PLC Operation

The operating status and stop status of the MICRO-EH can be switched through various types of operations. This feature is shown in Figure 9.1.

Cancel operation definition input

		Switch “RUN” and
		operation definition
Switch “RUN”		input “ON”
Stop status	Operating status	Stop status
Switch “STOP”		Switch “STOP” or
		operation definition
		input “OFF”
Designate operation definition input

		Caution
		The MICRO-EH cannot handle a REMOTE
		specification. A 10-point type CPU becomes
		the RUN mode when the RUN input is On.

Figure 9.1 Transitional diagram between operating and stop statuses

The MICRO-EH can be operated or stopped under the conditions as shown in Figure 9.1. If an error is detected during operation or stop, output is shut off, an error is displayed and the MICRO-EH stops. There are fatal error, serious error, minor error and warning. The operating status for each error is listed in Table 9.1.
