Table 4: Types Of Application - WAGO I/O-SYSTEM 750 Manual

14 Device Description
Ex i I/O modules shall only be supplied via Ex i 24 VDC power supply
module!
Ex i I/O modules shall only be operated with an Ex i 24 VDC power supply
module.
Do not exceed maximum current via power contacts!
The maximum current available from the Supply Module Ex i (750-606 or 750-
625/000-001) is 1 A.
When configuring the system, ensure that this current is not exceeded.
If exceeded, an additional potential feed module must be used.
The assignment of the connections is described in the "Connectors" section.
Connection examples are shown in section "Connect Devices" > ... >
"Connection Example(s)".
The input signal is electrically isolated and is transmitted with a resolution of
12 bits.
Simple parameterization of the HART I/O module for 6 different operating modes
enables the I/O module to be used optimally for 3 different types of application.

Table 4: Types of Application

Types of Application for the HART I/O Module
1 Programmable fieldbus controllers can communicate with HART devices
from IEC61131-3 programs using the "WagoLibHART_0x.lib" PLC library.
2 Up to 4 HART dynamic variables (PV, SV, TV, QV) can be incorporated in
the cyclic process image of the 750-333 PROFIBUS Coupler or 750-833
PROFIBUS Controller by parameterization via GSD (device master data) or
WAGO-I/O-CHECK 2.
3 When using the 750-333 PROFIBUS DP/V1 Coupler or 750-833
PROFIBUS Controller and the 759-360 PROFIBUS/HART Gateway DTM,
FDT tool routing is possible to the DTM of the connected HART device.
Any configuration of the I/O module is possible within an intrinsically safe
segment when configuring the fieldbus node. An arrangement in groups within
the group of potentials is not necessary.
The HART I/O module can be used with all couplers and controllers of the
WAGO-I/O-SYSTEM 750 listed in the following table "Compatibility List".
