14.2 Modbus – Overview
Modbusisabussystemforconnectingahost(e.g.PLC)andseveralslaves(e.g.elddevices).
DatatransmissionviatheModbuscommunicationprotocoltakesplaceindierentoperating
modes:
•
Modbus ASCII (data transmission as ASCII signs)
•
Modbus RTU (data transmission is binary signs)
A version of the Modbus protocol is the Levelmaster protocol.
Thedataexchangebetweenelddeviceandhostisdoneviaregisters.Theinputregistersonlyal-
low read access, holding registers both read and write access.
Thedevicesupportstheabovementionedpoints.Thefollowingshowsthedevice-specicdetails
required for this.
