Using Opc Ua Client - WAGO 765-1505/100-000 Product Manual

765-1505/100-000
While the Force function is enabled, the watchdog timer needs to be triggered regularly.
Triggering occurs each time an input simulation and output method is called. The watch-
dog timer is also triggered when the "AssignedForceID" node is read. This means that
regular reading of the "AssignedForceID" node triggers the watchdog timer and keeps the
Force function active.
To terminate the Force function, the OPC UA client calls the "DisableForcing" method, us-
ing the previous Force ID again. This makes value of the Force ID invalid. The OPC UA
client or another instance can request a new Force ID from the product in order to reen-
able the Force function.

with an OPC UA client.

An OPC UA client can have read access to the module with the authentication "anony-
mous." An OPC UA client can have read and write access to the module with the authen-
tication "username and password" if the user in question has write permission.
