Commissioning
This section shows a step-by-step procedure for starting up exemplarily a WAGO
fieldbus node.
8.1
Planning
The node is planned in accordance with the physical arrangement of fieldbus
coupler/controller and I/O modules.
The fieldbus coupler/controller or process data channel is to be configured on the
first slot.
The other slots are configured according to the physical arrangement of the I/O
modules. Only I/O modules with process data are relevant. The supply modules
without diagnostics, bus power supply module, field side connection module,
separation module and end module are not used for configuration because they
do not provide any process data.
Depending on the I/O module, there are 1 or 2 modules available in the hardware
catalog.
The I/O modules appear as 750-xyz ..., e.g. 750-400 2 DI/24 V DC/3.0 ms.
For all digital I/O modules with a channel granularity of 2 and 4, the entry
*750-xyz ... is listed.
When using these configuration modules, the fieldbus coupler/controller adds the
binary information of the current I/O module to a byte previously opened with
750-xyz ....
The use of a “*” configuration module is only permitted when the information
available is less than or identical to the remaining bits in the previously opened
byte.
The digital I/O modules combined in one byte can be spatially separated from
each other. There can be digital I/O modules of another signal type or byte-
oriented I/O modules between the modules.
To configure the scope of the available peripheral devices individually and
independently of the control program, it is possible to parameterize the I/O
modules in the configur
ation table as “(optional) no plug fitted”.
In this manner, the process data still on the PROFIBUS DP can be filtered for the
individual I/O module and not transmitted to the periphery or read by it.
