				D9187).
				• Turn on if the TEST mode is not established in response to a
M9078	TEST mode request	ON	: Abnormal	TEST mode request from a peripheral device.	S(Occur an error)
	error flag	OFF	: Normal	• When this relay turns on, the error content is stored at the
				TEST mode request error register (D9182 to D9183).

M9216	CPU No.1 MULTR	OFF to ON :		• Turn on when the data read from CPU No.1 is performed
	complete flag	CPU No.1 read completion		normally by MULTR instruction.
M9217	CPU No.2 MULTR	OFF to ON :		• Turn on when the data read from CPU No.2 is performed
	complete flag	CPU No.2 read completion		normally by MULTR instruction.	S(Read completion)
M9218	CPU No.3 MULTR	OFF to ON :		• Turn on when the data read from CPU No.3 is performed
	complete flag	CPU No.3 read completion		normally by MULTR instruction.
M9219	CPU No.4 MULTR	OFF to ON :		• Turn on when the data read from CPU No.4 is performed
	complete flag	CPU No.4 read completion		normally by MULTR instruction.
		OFF	: CPU No.1 reset	• Turn off at reset release of the CPU No.1.
				• Turn on during reset of the CPU No.1. (It also contains when a
M9240	CPU No.1 reset flag		release
				CPU is removed from the base unit.)
		ON	: CPU No.1 resetting
				• The other CPU is also resetting.
				• Turn off at reset release of the CPU No.2.
		OFF	: CPU No.2 reset	• Turn on during reset of the CPU No.2. (It also contains when a
M9241	CPU No.2 reset flag		release	CPU is removed from the base unit.)
		ON	: CPU No.2 resetting	• The error of the "MULTI CPU DOWN" (error code : 7000)
				occurs in the other CPU.
				• Turn off at reset release of the CPU No.3.
		OFF	: CPU No.3 reset	• Turn on during reset of the CPU No.3. (It also contains when a
M9242	CPU No.3 reset flag		release	CPU is removed from the base unit.)
		ON	: CPU No.3 resetting	• The error of the "MULTI CPU DOWN" (error code : 7000)
				occurs in the other CPU.
				• Turn off at reset release of the CPU No.4.
		OFF	: CPU No.4 reset	• Turn on during reset of the CPU No.4. (It also contains when a	S(Change status)
M9243	CPU No.4 reset flag		release	CPU is removed from the base unit.)
		ON	: CPU No.4 resetting	• The error of the "MULTI CPU DOWN" (error code : 7000)
				occurs in the other CPU.
		OFF	: CPU No.1 normal	• Turn off when the CPU No.1 is normal. (It contains at
M9244	CPU No.1 error flag	ON	: On CPU No.1 stop	continuation error.)
			error	• Turn on during stop error of the CPU No.1. (Note-1)
		OFF	: CPU No.2 normal	• Turn off when the CPU No.2 is normal. (It contains at
M9245	CPU No.2 error flag	ON	: On CPU No.2 stop	continuation error.)
			error	• Turn on during stop error of the CPU No.2. (Note-1)
		OFF	: CPU No.3 normal	• Turn off when the CPU No.3 is normal. (It contains at
M9246	CPU No.3 error flag	ON	: On CPU No.3 stop	continuation error.)
			error	• Turn on during stop error of the CPU No.3. (Note-1)
		OFF	: CPU No.4 normal	• Turn off when the CPU No.4 is normal. (It contains at
M9247	CPU No.4 error flag	ON	: On CPU No.4 stop	continuation error.)
			error	• Turn on during stop error of the CPU No.4. (Note-1)

(Note-1): The CPU No.1 is reset after the factor of the stop error is removed to cancel a stop error. Resetting is cancelled.
