The function and protocol for each type of port that you can
select is briefly described below. For more information on
using the Serial Ports command see Section 4, Working with
Projects, in the Regent User’s Guide.
Comm
Supports the Regent R2 protocol for point-to-point
communications between the Regent and the computer
running the W
INTERPRET application. Some third-party Man-
Machine-Interface (MMI) products and DCS gateways may
also support point-to-point communications using the Regent
R2 protocol.
Multidrop
Supports Regent R2 protocol for multidropped Regents
connected to a PC running the W
INTERPRET application (or
other third-party supporting products and gateways). Ports
configured for multidrop communications require a node
number.
ASCII
Used by the Regent to transmit ASCII output messages to
external serial equipment such as printers and VDUs. ASCII
output messages are programmed using the ASCII output
element in ladder logic function blocks.
