Sub-Index 0
Sub-index 0 = 0: Mapping of virtual modules not active
Sub-index 0
≠
0 Mapping in of virtual modules active
The entry indicates the number of the connected modules in the maximum
configuration.
When changing the value from 0 to >0, the configuration is created as de-
scribed from sub-index 1. During the creation of a new configuration, all pre-
viously configuration settings that have not been permanently stored, will be
written over and the process image reset. For this reason, always configure in-
dex 0x4500 first, followed by all other settings (mapping, sync time,...).
Setting the sub-index 0 is only possible in the
Pre-Operational
status.
If the creation of a new configuration is free from errors, an Emergency is sent
with the parameters PP=LL=SS=0.
If an error occurs during the creation of a new configuration (i.e. the number
of connected modules exceeds that of the modules configured), a correspond-
ing Emergency is transmitted. The coupler starts with the default configura-
tion in accordance with the modules connected, and changes to the STOP
status.
