Programming Information The first four chapters of this book cover the basic details of installation, operation and configuration. The remainder of the chapters describe diagnostics and messaging features that can be included in the PLC application program that controls the operations of the FIP Bus Controller. Utilizing Point Faults and Network Diagnostics The application program in the Series 90-70 PLC can take advantage of conventional point fault and alarm contacts, plus additional fault contacts that have been defined specifically for FIP. These Subscriber Fault Contacts can be used to identify faults reported by devices on the FIP network. See chapter 5 for details. In addition to point faults in the PLC’s fault table, the FIP Bus Controller normally logs loss of bus faults for its own connections to the FIP network as well as for all configured remote I/O and generic devices. This capability can be extended by sending the FIP Bus Controller a Start Network Diagnostic COMREQ from the application program. The FIP Bus Controller will begin periodically updating a specified area in PLC memory with network presence and bus fault information for devices on the FIP network. See chapter 8 for more information.

Establishing Communications Channels 

The Series 90-70 PLC can maintain up to 32 individual communications channels through which it exchanges data with other PLCs or controllers via TCP/IP protocol. The application program can use Communications Request (COMREQ) instructions to open, re-task, or abort these communications channels. Once opened, a communications channel can remain open indefinitely or for a specified duration. Chapter 7 gives the details of programming communications channels. Chapter 6 gives general instructions for programming Communications Requests to a FIP Bus Controller. Sending and Receiving Generic FIP Messages Normally, the FIP Bus Controller ignores any FIP messages on the FIP Network. However, it is possible to send and receive FIP messages via the FIP Bus Controller. Chapter 9 explains how the application program can use Communications Requests to the FIP Bus Controller to:
Receive State Change messages from remote I/O devices and place them in a specified area of memory in the Series 90-70 PLC
Receive other FIP messages from the network and place them in a specified area of memory in the Series 90-70 PLC
Send FIP messages on the network
