Because the relay that normally provides the processing signal has been reconfigured
for voltage control, the Fail and Pass signals have been reconfigured to provide Pass,
Fail, and Processing signals. The different states of the Fail and Pass signals are
described in the truth table below.
For questions related to the standard configuration of the PLC remote, please refer to
the section titled
Connection of Remote I/O in the Operations manual.
52 15 Remote Memories Select (8204, 8254, 8206, 8256, 8207, 8257)
(Discontinued)
The 15 Remote Memories Select option increases the number of files that may be
accessed through the Input remote control connector. Fifteen pre-programmed test
files can be accessed by connecting pins 1,6,8, and 9 to the common pin 7, in
different combinations. The
Remote File Select Truth Table (binary) shows the
different combinations of momentary switch (relay) closures, and which memory
programs that will be selected as the result. It may be necessary to "OR" the
momentary switches (relay contacts) to prevent incorrect program selection due to
timing errors.
