The data type and size of the data transmitted via an unsolicited message must match exactly the type and size configured for the CIMPLICITY point to be used for this data. For example, if ten 16-bit unsigned analog values are being transmitted in a message, a CIMPLICITY data structure Type of UINT with an Element attribute of 10 (ten) will be required. Messages that do not conform will cause an error code to be generated, and the data point will not be updated.
When multiple devices route unsolicited messages through the same PLC 5/250 to the same CIMPLICITY device communications process, and use the same application address, the data type and size of the messages must match exactly the type and size configured for the CIMPLICITY point.
Note: If possible, you should use unique application addresses for all messages being routed through a specific PLC 5/250.
