Acronym for Programmable Controller Communication Commands.
PGM (Program)
PGM setting means the baud rate is set via an explicit message request
over the network by another device (typically a configuration tool,
such as a PC or DeviceView). This baud rate setting is retained by the
daughtercard when the power is cycled on the PanelView terminal.

programmable controller
A solid-state control system that has a user-programmable memory for
storage of instructions to implement specific functions such as I/O
control, logic, timing, counting, report generation, communication,
arithmetic, and data file manipulation. A controller consists of a
central processor, input/output interface, and memory. A controller is
designed as an industrial control system.
real time clock
