With Plc Library On All Compatible 75X-Xxx Fieldbus; Couplers/Controllers; Communication On 75X-Xxx Via Plc Library - WAGO I/O-SYSTEM 750 Manual

66 Commissioning
9.1 With PLC Library on All Compatible 75x-xxx
Fieldbus Couplers/Controllers
With the default parameter settings "2 AI + 6-Byte Mailbox", the HART I/O
module can be used with all WAGO fieldbus couplers/controllers 75x-xxx of the
WAGO-I/O-SYSTEM with HART functionality, which are listed in the Section
"Compatibility List".
Note the maximum number of connectable I/O modules!
Because of the process data capacity of the HART I/O module, please be sure to
take into account the corresponding maximum number of modules that can be
connected when using a WAGO fieldbus coupler/controller 75x-xxx. You can find
this number in the table "Compatibility List".
In the cyclic process image of the fieldbus coupler/controller, the HART I/O
module appears as a 1-channel I/O module whose process values consist of the
analog values and a 6-byte mailbox. HART communication can then take place
via the mailbox.
Library for HART functionality required!
To use the HART functionality, it is necessary to install and incorporate the
WAGO HART library "WagoLibHART_0x.lib" in the PLC application.
More information for downloading the library
You can download the "WagoLibHART_0x.lib" library on the WAGO homepage
at: www.wago.com
Enter the search term "WagoLibHART".
9.1.1

Communication on 75x-xxx via PLC Library

Communication between the 75x-xxx fieldbus couplers/controllers and the HART
I/O module is achieved using the "WagoLibHART_0x.lib" library.
This library enables easy access to the 6-byte mailbox of the I/O module and
provides the necessary HART commands, which can then be executed locally
from the PLC application.
