Functions with an Extension Module Connected

The main D/A converter module permits one extension module to be connected.
● Before replacing the extension module, turn off the module power supply. Disconnecting the extension module during the
power-on of the module power supply results in the error code (1F00H) being stored into Latest error code (RWr0), Error
flag (RXA) turning on, and the ERR. LED lighting up, which stops the operation.
● After replacing the extension module, write the parameters again.

Available functions with an extension I/O converter module
connected
Here is the list of the available functions with an extension I/O module connected:
External power supply monitoring function
External signal assignment function
Digital output HOLD/CLEAR setting function
(referred to as the output HOLD/CLEAR setting function in the manual of I/O modules)
Input response time setting function
Number of ON times integration function
(1) External power supply monitoring function
This function monitors the on/off state of the external power supply with the I/O PW LED of an extension output
module indicating the state.
By using External power supply monitor request flag (RY1F), a moderate error is generated when the external
power supply is off. Thus, the ON/OFF status of the external power supply is notified and the extension output
module can be stopped.
(a) External power supply monitoring function
While External power supply monitor request flag (RY1F) is on, power off of the external power supply causes
a moderate error. When using this function, check that the external power supply stabilizes before turning on
External power supply monitor request flag (RY1F). When turning off the external power supply, turn off
External power supply monitor request flag (RY1F) in advance.
(b) Setting and checking the external power supply monitoring function
