7.2.7 The Auxiliary Tab
The Auxiliary tab is used for configuring the auxiliary port. This port is configured in the same fashion as the PLC
communications port. Special drivers are needed for this port. This port does not support AB DH485 or TELEMECANIQUE
UniTelWay communications.
Aux. type
: Select the type of PLC from
available PLC selection menu. The dropdown
displays all of the PLC drivers available. These
drivers are located in the
\Drivers
-
SubDirectory with the *.pds extension. Select
the driver that matches your PLC’s protocol.
Serial Port I/F
: Select
the Auxiliary port’s
type of hardware
communications. The
HMI activates the corresponding port pins. Only
RS232 and 2 wire RS485 configurations are
available.
Note:
For additional information about
communication configurations for a selected
PLC, see the
Controller Reference
Guide
section that refers to that PLC.
Note:
The
AUX[RS-485] PC[RS-232]
port is a
dual port.
Baud rate, Parity, Data bits and Stop bits
: Set
the baud rate to match the PLC ports settings.
Comm. delay and Additional Parameters
:
The Comm. delay parameter is used for setting an interval between communications requests to the controller. Enter a
number from 0 to 999. The number specifies the 10-millisecond intervals between communications. Foe example: a setting
of 100 puts a 1-second interval between communications requests. This parameter will slow data update rate on a window. It
also gives slow controllers a way to meet processing demands without too many interruptions.
Set the other additional parameters as required by your driver. See the
Controller Reference
Guide
section that references
the PLC driver for further details.
