Programming the PFC with WAGO-I/O-PRO 32
Due to the IEC 61131 programming of the ETHERNET TCP/IP fieldbus con-
troller 750-842 you have the option to use the functionality of a PLC beyond
the functions of fieldbus coupler 750-342.
An application program according to IEC 61131-3 is created using the pro-
gramming tool WAGO-I/O-PRO 32.
This manual, however, does not include a description of how to program with
WAGO-I/O-PRO 32. In contrast, the following chapters are to describe the
special modules for WAGO-I/O-PRO 32 for you to utilize explicitly for pro-
gramming the ETHERNET TCP/IP fieldbus controller.
The description also deals with the way of transmitting the IEC 61131-3 pro-
gram into the controller and loading a suitable communication driver.

WAGO-I/O-PRO 32 manual (order No.: 759-122 / 000-001).
3.2.7.1 WAGO-I/O-PRO 32 library elements for ETHERNET
You are offered various libraries for different IEC 61131-3 programming ap-
plications in WAGO-I/O-PRO 32. They contain modules of universal use and
can, thereby, facilitate and speed up the creation of your program. As standard,
the library ’standard.lib’ is available to you.
The libraries described in the following are specifically intended for
ETHERNET projects with WAGO-I/O-PRO 32:
•
"ETHERNET. lib"
(contains elements for the ETHERNET fieldbus communication),
•
"EtherTCPmodbus.lib"
(contains elements for the MODBUS TCP fieldbus communication) and
•
"Internal types for EtherTCPmodbus.lib"
(contains elements for an easier access to the MODBUS/TCP requests und
responses).
These libraries are loaded on the WAGO-I/O-PRO CD.
Having integrated these libraries, you have access to their POUs, data types
and global variables which can be used in the same manner as those defined by
yourself.
