Details of output signals

This section describes the details of the output signals for the pulse input module that are assigned to the CPU module.
The I/O numbers (X/Y) described in this section are for the case when the start I/O number of the pulse input module is set to
0.
This section describes I/O signals and buffer memory addresses for CH1. For details on the I/O signals and
buffer memory addresses for CH2 and later, refer to the following.

Page 65 Buffer Memory Areas
Operating condition setting request flag
When the buffer memory values are changed, turn on and off this signal to enable the changed settings.
For the timing of turning on and off the signal, refer to the following.
Page 60 Operating condition setting complete flag
For details on the buffer memory items to be enabled, refer to the following.
Page 65 Lists of buffer memory addresses
Turning on this signal resets the following buffer memory areas.
• 'CH1 Sampling pulse number' (Un\G0)
• 'CH1 Accumulating count value' (Un\G2, Un\G3)
• 'CH1 Input pulse value' (Un\G4, Un\G5)
• 'CH1 Overflow detection flag' (Un\G6)
• 'CH1 Carry over detection flag' (Un\G7)
• 'CH1 Warning output flag' (Un\G8)
• 'CH1 Error code' (Un\G9)
• 'CH1 Alarm code' (Un\G10)
■Clearing errors and alarms
Turning on this signal clears errors and alarms. 'CH1 Error occurrence' (X8) turns off and 'CH1 Error code' (Un\G9) and 'CH1
Alarm code' (Un\G10) are cleared to 0.
■Device number
The following shows the device number of this output signal.
Signal name
Operating condition setting request flag
■Operation timing
The change is enabled on the rising edge (OFF  ON) of the signal.
CH1 Error reset request
When an error occurs and 'CH1 Error occurrence' (X8) is on or when an alarm occurs, turning on and off this signal
corresponding to the relevant channel clears the error and alarm.
For the timing of turning on and off the signal, refer to the following.
