Input Signals

Input Signals
Data Register Number		Signal Name	Description
Channel 1	Channel 2
Xn.0	Xn.F	DPRAM ACK	This is a response to request DPRAM (Yn.3/Yn.B). When the contents of DPRAM are set to the module, this is set.
Xn.1	Xn.8	Counted Value Greater 1	If the current value is greater than the set coincidence comparison value 1, this is on.
Xn.2	Xn.9	Counted Value Coincident 1	If the current value is equal to the set coincidence comparison value 1, this is on.
Xn.3	Xn.A	Counted Value Less 1	If the current value is less than the set coincidence comparison value 1, this is on.
Xn.4	Xn.B	Detect Request for Outer Presetting	When the signal to preset is detected from the outer input terminal, this is set and latched. If the request to reset detect outer presetting (Yn.5/Yn.D) is set, this is reset.
Xn.5	Xn.C	Counted Value Greater 2	If the current value is greater than the set coincidence comparison value 2, this is on.
Xn.6	Xn.D	Counted Value Coincident 2	If the current value is equal to the set coincidence comparison value 2, this is on.
Xn.7	Xn.E	Counted Value Less 2	If the current value is less than the set coincidence comparison value 2, this is on.

Output Signals

Output Signals
Data Register Number		Signal Name	Operation Timing	Description
Channel 1	Channel 2
Yn.0	Yn.8	Requesting to Reset Coincidence Signal 1		When set, this will reset Counted Value Coincident 1.
Yn.1	Yn.9	Requesting to Preset		When set, this will turn on the preset.
Yn.2	Yn.A	Enable Coincidence Output		When set, this will output Counted Value Coincident 1 and Counted Value Coincident 2 to the outer terminal.
Yn.3	Yn.B	Request DPRAM		When set, DPRAM will become available.
Yn.4	Yn.C	Enable Count		When set, counting will be enabled.
Yn.5	Yn.D	Requesting to Reset Detect Outer Presetting		When set, Detect Request for Outer Presetting is reset.
Yn.6	Yn.E	Requesting to Start Counting		When set, the latch or sampling counting function begin.
				When set, counting or periodic pulse counting are disabled.
Yn.7	Yn.F	Requesting to Reset Coincidence Signal 2		When set, this will reset Counted Value Coincident 2.

Allocation Example

CM3-SP02HSC

The CM3-SP02HSC is allocated one WORD of X (Xn.0 ~ Xn.F) and one WORD of Y (Yn.0 ~ Yn.F).

n is a number representing the CM3-SP02HSC's position within the chassis.

To access the X memory registers for this CM3-SP02HSC example, the X value range is X2.0 ~ X2.F.
To access the Y memory registers for this CM3-SP02HSC example, the Y value range is Y2.0 ~ Y2.F.

CM3-SP02HSD

The CM3-SP02HSD is allocated one WORD of X (Xn.0 ~ Xn.F) and one WORD of Y (Yn.0 ~ Yn.F).

n is a number representing the CM3-SP02HSD's position within the chassis.

To access the X memory registers for this CM3-SP02HSD example, the X value range is X3.0 ~ X3.F.
To access the Y memory registers for this CM3-SP02HSD example, the Y value range is Y3.0 ~ Y3.F.
