Overview

The library contains function blocks that permit the exchange of data between the BC9xxx Bus Controller and a remote partner on the MODBUS/TCP port.

Comments

• The number of IP connections that may be open simultaneously is restricted to four, in order to maintain the use of resources at a minimum. If it is necessary to establish a further connection, a connection that is not required must first be closed.
• After about 10 seconds, a connection that has not been used during that period is automatically closed, and must be reopened if needed.
