3 Input/Output Signals
3.3 PLC Device Assignment of Digital Signal (DI/DO)
Note
(1) However, the alarm "Y05 Initial parameter error" caused by the above issues will not occurs in the following cases:
- "0" has been set to the target channel.
- Remote I/O unit with DI/DO function are not connected to the station which has been specified with the target channel
and station number.
- The parameter "#1238 set10/bit3" is ON (the input from RIO is ignored).
(Example) The power is turned ON in a state where the X100 and X200 of PLC device are set redundantly to the RIO
assignment parameter #1 to #5 as shown in the table below.
(All stations which has been set to the RIO assignment parameters #1 to #5 are connected to NC control unit.)
Parameter set No.#n
#n (parameter No.)
1 X (#53013)
2 X (#53023)
3 X (#53033)
4 X (#53043)
5 X (#53053)
Result:
The parameter number (53034) of "DI device No. #3" will be displayed on the alarm "Y05 Initial parameter error".
Duplication error of X200 will be detected first because the RIO assignment parameter is checked from the top. Between
the parameter set #2 and #3 to which the X200 are set, parameter set #3 which is the latter will be displayed as the alarm.
