I.6 Remote (PLC) Channel Monitoring
Function
The unit shall continuously scan all properly configured Remote Channels. The
unit shall monitor remote channels which physically reside in other industrial
equipment interfaced to the Verbatim via the serial interface. The unit shall be
capable of interfacing to at least two PLC networks simultaneously. The unit
shall be capable of monitoring any PLC data register regardless of register type,
whether digital, analog, input, output or status point. Alarm criteria shall be
settable according data register type. For digital remote channels, alarm criteria
shall be settable for normally ‘0’ or normally ‘1’. For analog remote channels,
both a high setpoint and a low setpoint alarm criteria shall be settable.
Violation of alarm criteria at any remote channel shall cause the unit to go into
alarm state and begin dial-outs. All remote channel alarm criteria shall be
settable either at the front panel of the unit of over the telephone using touch-
tone commands. The unit shall be capable of writing data to any PLC data
register to which writing data is a legal operation. The unit shall monitor any
failure of the active serial communications channels. Upon failure of any
communications channel the unit shall enter the alarm state and begin dial-outs.
The unit shall be capable of transferring data between one remote channel on
one serial communications network and another remote channel on a second
serial communications network. The unit shall also be capable of transferring
data between remote channels on a serial communications network and physical
channels within the unit. The unit shall be optionally upgradable to incorporate
provision for 32, 64 or 96 total remote channels.
