! ! ! ! ! External Input Signal
The PL's RAS interface connector uses the following input signals.
Standard Signal Input (DIN)
This standard digital input is used for alarm detection in external devices. The
input signal uses two bits.
The System Monitor utility can be used to enable or disable this feature, as well as
designate what type of processing is to be performed once a signal is received.
Remote Reset Input
This is the reset signal sent from an external device to the PL. When this signal is
enabled, a forced reset of the PL is performed.
The System Monitor utility can be used to enable or disable this feature
