Fiedlbus parametrization vacon • 29Local contacts: http://drives.danfoss.com/danfoss-drives/local-contacts/55.3.9 Connection limitDefines how many clients can access the server simultaneously.5.3.10 Unit Identifier numberThe Modbus 'slave address' field usually used on Modbus Serial Line is replaced by a single byte'Unit Identifier'.When the TCP is used as the communications protocol, the AC drive is addressed by its IP addressand broadcast messages are not possible. In this case, the unit identifier is useless. In the UDP, it ispossible to send broadcast messages and therefore the unit identifier becomes important.To keep things simple, the unit identifier is checked when using both TCP and UDP. In TCP you canuse value 255 (non-significant) as a unit identifier and send the messages to all slaves with thatvalue.5.3.11 Communication timeoutFor Modbus, this value defines the time in which a message must be received (from Client inModbus TCP/UDP) before a fieldbus fault is generated. If timeout is set to zero, no fault is created.5.3.12 IDMap IDsSee Chapter 6.3.8.P5.9.2.2.1.5 Illegal data values 0…65535 - - 2453 See 5.2.12P5.9.2.2.1.6 Slave device busy 0…65535 - - 2454 See 5.2.13P5.9.2.2.1.7 Memory parityerror 0…65535 - - 2455 See 5.2.14P5.9.2.2.1.8 Slave device fail-ure 0…65535 - - 2456 See 5.2.15P5.9.2.2.1.9 Last faultresponse 0 - - 2457 See 5.2.16P5.9.2.2.1.10 Control word - hex - 2458 See 5.2.17P5.9.2.2.1.11 Status word - hex - 2459 See 5.2.18Table 14.
