Note1) remote READY flag
If you change the DA setting or carry out a output permission/prohibition fom PLC side, it becomes ON When complete in the update processing after making this flag OFF. so that in the case of the output voltage carries out variable continuously, be careful so as not to choose an output permission / prohibition flag and AND.
Otherwise it will be connected with this graph and the output become 0 V voltage from the setting value voltage.
Note2) about A/D,D/A change permission/prohibition specification flag
When making PLC RESET from RUN, because it has rewritten this unit to the default value, apart from usual initialization procedure, always add ON, a remote READY flag and the AND circuit of the permission / prohibition specification setting. |
