An external HART request has been rejected because the channel is not the active channel of a
redundancy pair. The request must be sent to the connected 󹪝eld device via the partner module.
Example of HART programming (HART command interface)
For HART channel 0, command 01 is to be sent in transparent message format to the HART 󹪝eld
device with address "98 CF 38 84 F0".
A positive edge at input 4.0 of a digital input module leads to the writing of the HART command.
The following assumptions are made:
• The module address of the I/O module is 512 (200
H
).
• The data record is stored in DB80: starting from address 0.0, length of 11 bytes.
• In this example, DB80 (request data record for channel 0) consists of 11 bytes.
