Setting up direct driver
communications
RSView32 ™ uses a direct connection to the drivers in RSLinx ® to
communicate with most Allen–Bradley ® devices, as well as
SoftLogix ™ 5 devices. This chapter describes how to set up direct
driver communications.
You can also use DDE (Dynamic Data Exchange) or OPC ® (OLE for
Process Control) to connect to third-party devices or servers, as
described in Chapter 3, Setting up OPC and DDE communications.
You must use an OPC or DDE connection to handle unsolicited
messages and to communicate with the PLC–5
® /250 or
ControlLogix ® 5550 device. For instructions on using unsolicited
messages see RSView32 Technical Notes on the RSView32 Tools
menu.
