StruxureWare Building Operation uses the old PI-Modbus-300 protocol

Issue

StruxureWare Building Operation uses the old PI-Modbus-300 protocol

Environment

StruxureWare Building Operation using Modbus protocol

Cause

Does StruxureWare Building Operation use the MODICON protocol with the reference PI-MBus-300?

Resolution

Modicon was purchased by Groupe Schneider (which eventually became Schneider Electric) in 1996, way before Schneider Electric bought TAC.
The PI that referred to is just a prefix of the technical document describing the Modbus communication protocol. The 300 is the version of the protocol.
StruxureWare Building Operation supports a subset of the Modbus protocol. StruxureWare Building Operation does not support all Functions defined by the document specified. Modicon is still the only one that does.
