Device names are not case sensitive, and at least one space character must be between each parameter specification.
The connection description must always be specified in quotation marks ("...") in the object description.

Response timeout for SNMP data in milliseconds The response timeout specified here is used to monitor the response times for SNMP read or write tasks. For SNMP broadcast telegrams (determination of the MAC addresses for all PLCs that can be reached), response data is waited for throughout the duration of the response timeout. Typical response timeout values range from 500 to 2500 ms. |
