6. Check the installation status of I/O modules.
– Only the currently installed I/O modules are shown. Check that the
details of each station (ST#) are the same as the installation status
of I/O modules.
– The meanings of the columns are as follows:
– The following combination of boards is displayed in this example.
ST#00: JANCD-YI021-E board
This board is shown as YSF21 on the IO module
display.
(Digital input 40 points, digital output 40 points)
This board is fixed to ST#00.
ST#01: JANCD-YEW01-E board
(16 contact inputs, 16 contact outputs, 2 analog inputs,
2 analog outputs)
Note that even though 16 contact inputs and 16 contact
outputs are displayed, they cannot be used for external
devices because they are used by the system.
Switch S1: Set to 1. (This value is the value of ST#.)
ST#
Station number of I/O module
DI
Number of contact inputs
1)
1 If “-” is displayed, the corresponding input or output is not
implemented.
DO
Number of contact outputs
AI
Number of analog inputs
AO
Number of analog outputs
BOARD
Board type
2)
2 If the board type cannot be determined, “*****” is displayed
in the BOARD column. Even so, there is no problem as
long as the values of DI, DO, AI, and AO are normal.
