3.5 Wiring of RS–485 ports
CAUTION
Wiring RS–485 cables to this equipment is easy, but it is also easy to do it
wrong and end up with a non-working Modbus network or, even worse, a
damaged Transclinic. All the units shipped out from Weidmüller have their
RS–485 ports thoroughly tested right at the end of the production line.
Weidmüller will not cover under warranty Transclinic units that have their
RS–485 transceiver IC damaged due to wrong wiring and/or due to surges.
CAUTION
RS–485 wiring requires technical skills and tools different to those
of available to regular electricians. Please ensure that this step of the
equipment installation is performed by staff with the right skills and tools.
This user guide cannot be a replacement for field bus wiring experience
and Weidmüller cannot be made liable for any damages resulting from
improper wiring.
CAUTION
This equipment complies with the latest RS–485 and Modbus standards,
which are the official sources of information. The installation staff must
refer to the following documents, which always have priority over any
wiring recommendations given in this user guide:
• TIA/EIA–485–A: “Electrical characteristics of generators and receivers
for use in balanced multipoint systems”
• TIA TSB–89–A: “Application guidelines for TIA/EIA–485–A”
• “Modbus application protocol specification” v1.1b
• “Modbus over serial line specification and implementation guide” v1.02
