4.0 PROGRAMMING
The sections that follow describe using the PC Link module as a drop
on aDCS/AutoMax Network or aRemote I/O network. After the PC
Link module has been installed in the personal computer and the
INSTALL program has been run to configure the port address and
memory location (see section 3.1.5), the module can be used for
either DCS/AutoMax network or remote I/O network applications.
However, it can be configured for only one application at a time. To
switch applications, simply run the appropriate batch file (NET.BAT or
RIO.BAT). If you are using the PC Link module on a DCS/AutoMax
network, you must assign the drop and drop depth using your device
driver program. If you are writing your own device driver for
DCS/AutoMax Network communication, or are using the PC Link
module on aremote I/O network, refer to Appendix D.
4.1 DCS/AutoMax Network Communications
(RENET)
Loading the Network Communications software (RENET) onto the PC
Link module enables it to function like a Network Communications
module (M/N 57C404). The PC Link module can act as any valid
drop, except the Master (drop 0), and can have any valid drop depth.
The drop and drop depth are assigned by the device driver. Refer to
your device driver program documentation for the procedure used to
assign the drop number and drop depth.
4.2 Remote I/O Network Communications
(RERIO)
Loading the Remote I/O software (RERIO) onto the PC Link module
enables it to function like a Remote I/O Communications module
(M/N 57C416). When configured as a passive drop, the PC Link
module can monitor all drops on a remote I/O network, accessing the
output data being sent from the Master to the Slave drops as well as
the input data being sent from the Slave drops back to the Master.
When configured as an active drop (for network simulation), the PC
Link module will receive output data from the Master and send input
data back to the Master. The PC Link module can act as any valid
drop. Refer to Appendix D for the procedure used to configure the
drop number.
4.3 Register Configuration
Registers controlled by the PC Link module are defined as network
variables. If you are using the AutoMax Programming Executive
version 3.0 or later, you define these registers only in the racks that
access the PC LinkĆcontrolled registers. If you are using the PC Link
module only to monitor the network, you do not need to define the
PC Link registers in the AutoMax Programming Executive.
If you are using the AutoMax Programming Executive version 2.1 or
earlier, you define registers (using NETDEFs) in the configuration task
for the rack that will access the PC LinkĆcontrolled registers. If you are
using the PC Link module only to monitor the network, you do not
need to define the PC Link registers in any configuration task.
