(8) Cyclic data update watch time setting
This signal is used to set the time to monitor the data update interval of the cyclic transmission (watch time).
A cyclic transmission stop state that persists over the cyclic data update watch time is regarded as being in
disconnection, where the output status of the extension output module becomes HOLD (1H) or CLEAR (0H)
according to Digital output HOLD/CLEAR setting (address: 0011H). For Digital output HOLD/CLEAR setting
(address: 0011H), refer to the following:
• Digital output HOLD/CLEAR setting ( Page 213, Appendix 3 (10))
(a) Setting range
Setting range is Not monitor (0) or 0.1 to 2 seconds (1 to 20). Set the value in increments of 100ms (1).
(b) Enabling the setting
Turn on and off Initial data setting request flag (RY9) to enable the setting.
(c) Default value
The default value is Not monitor (0).
(d) Remote buffer memory address
The remote buffer memory address of this area is as follows:
● Setting a value out of the range results in the error code (0930H) being stored in Latest error code (RWr0), Error flag
(RXA) turning on, and the ERR. LED lighting up, with the I/O operation stopping.
● Synchronous communication mode ignores the set value, resulting in operation with Not monitor (0).
