Special Modules
If WAGO and external devices in different modes are connected with a
WAGO master, the following guidelines apply for communication with each
other (see Table 15):
Table 15: Possible connection of a master with WAGO or external slaves
Master
Real-time profile
Ad hoc profile
In the master, slots 1 through 7 correspond to the entries in the table of
WAGO devices. In the ad hoc profile, slots 8 through 13 are added with the
table entries for external devices.
In the ad hoc profile, connections to a maximum of seven slaves are estab-
lished. Of these, a maximum of six can be (see Table 15) WAGO slaves and a
maximum of six can be external devices. By using up the tables for external
and WAGO devices, process image areas can be configured for up to 13 slots
in the master.
Note
When changing to the ad hoc profile, care must be taken that the real-time
device is not connected to slot 7. If a device with a "cutoff" greater than zero
is configured, slot 7 is filled with zeros in the process image.
In the slave, the process image always contains only one slot in which the con-
figured master is unmasked. The width of a slot is determined by the "cutoff"
of this slot.
