TOA IP Intercom Compatibility and System Limits

Compatibility

S4S OPC server TOA v1.0.0.3

Desigo CC V3.0 or higher

Size Limits

Since no specific limits are identified for this integration, refer to Desigo CC system limits defined in the System Description document (A6V10415500).

Configuration Limits

By default, the S4S OPC server provides values -1 as default value for normal or not initialized statuses for some of its tags.

Since Desigo CC cannot enumerate negative values for the corresponding texts statuses, in the S4S OPC server it is necessary to change the Default Value TAG to 900 (highlighted in the following figure). The option to change the value is available in the Configuration Parameter menu of the S4S OPC server TOA.
