Set up of master ports
set up of the master ports is possible using a sND_uD command, CI = 51 (hex)
with the following data field.
Data field DIF = 01 (hex) VIF = FD (hex) VIFE = E2 (hex) VIFE = 00 (hex) DATA
Description 8-bit integer Ext. coding Cont. signal Write replace Port setup
The DATA is coded according the following:
Value Master RS-232 port Master M-Bus port
00 (hex) Inactive Inactive
01 (hex) Inactive Active
02 (hex) Active Inactive
03 (hex) Active Active
Read out of master ports
Read out of the master ports setting is possible using a REQ_uD2 command.
AD-01 will respond with a RsP_uD, CI=72 (hex) with the following data field.
Data field DIF = 01 (hex) VIF = FD (hex) VIFE = E2 (hex) DATA
Description 8-bit integer Ext. coding Cont. signal Port setup
The DATA is coded according the following:
Value Master RS-232 port Master M-Bus port
00 (hex) Inactive Inactive
01 (hex) Inactive Active
02 (hex) Active Inactive
03 (hex) Active Active
Error indication
AD-01 includes possibilities to alert the supervision system of short-circuit or overload
on the M-Bus master interface. Readout of error status can be made using a REQ_uD2
command. AD-01 uses the status field in a RsP_uD answer sequence to alert possible
errors.
The coding of the status field is according to the following:
Value status field Description
00 (hex) No error
10 (hex) Overload / short-circuit of
M-Bus master interface
