SCANport Peripheral Interface
The 8720MC external SCANport connection uses the Port 2 address. It
can be used as a single connection to a remote HIM, a PC, or PLC. It
can also be connected to a 2 or 4 port expander as shown in Figure
4.1. The SCANport expander is very useful in situations where a PLC is
used as the source of the command reference and the logic interface.
The expander allows easy plug in of a personal computer running
DriveExplorer
for the purpose of displaying and/or modifying
parameters as well as monitoring process parameters while the
process is executing. The PLC interface is accomplished via a
SCANport adapter module connected to one of Rockwell’s
communication networks such as remote I/O, DeviceNet or
ControlNet. The 1203-GK5 module shown in Figure 4.1 is a stand
alone DeviceNet adapter. Use of a SCANport adapter module with a
PLC allows the control of position as well as velocity or torque. See
parameters 258, Target_Position, 259, Posn-Velocity and 260,
Posn_Accel _Rate in Appendix C for details.
