When "Status" is selected in the DIP switch settings of the wireless master
station, the status area that displays the wireless slave station status is avail-
able in the first two or four words of the input area in the Master. The contents
and causes of errors can be found by checking this area.
To be concrete, an error flag is allocated for each wireless station in the status
area, as shown in the following diagram.
1. When maximum number of I/O = 32 words/32 words:

Remedy
Check the switch setting and reset cor-
rectly. If normal operation is not restored,
it is possible that intermodulation is the
cause of the error. With reference to
Points for Consideration with Wireless
Systems on page 16, reset the frequency
to a level for which intermodulation does
not occur.
Check the settings and reset correctly.
Set the unit so the wireless communica-
tion is stabilized by changing the fre-
quency (WCH) or implementing the setup
test.
