Protocols and Communications Functions
The protocol and function supported for each port is
configured using the Serial Ports command from the Project
Editor’s Definitions menu in W
INTERPRET . An example of the
Serial Ports dialog is shown in Figure 4.
Figure 4. W INTERPRET ’s Serial Ports Configuration Dialog.
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.
Only COMM, ASCII and MODBUS (point-to-point
connection) can be directly interfaced to the real-time clock
communications module. The other communications
functions, which require multidrop connections, can be
configured for the module but require an external signal
converter to support the necessary RS422/485 multidrop
network.
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.
