6.2 APPENDIX 2: PROCEDURE ERROR CODES
The table below reports the error codes returned by the circuit module after the failure of a procedure.
Code Error
0
Auto-addressed loop mode initialization: line fault (overload or shortcircuit) at power on.
Check the electrical connections among the circuit module and the points connected directly
with LA and LB.
1
Auto-addressed loop mode initialization: unexpected voltage on line LB.
A voltage on LB terminals has been detected at the beginning of the initialization procedure; this
voltage is probably due to an unwanted connection between line LA and line LB (please, note
that it is necessary to place at least one point in series between LA and LB).
2
Auto-addressed loop mode initialization: lack of 4 consecutive addresses to assign to a multiple
I/O module.
3
Auto-addressed loop mode initialization: missing answer in current from the point or open line.
The procedure completes correctly when a voltage on LB is detected.
5
Auto-addressed loop mode initialization: missing answer from a point with invalid address.
The module could not communicate with the point: check the electrical connections.
6
Missing answer from a point with valid (1–128) address.
The module could not communicate with the point: check the electrical connections.
7
Auto-addressed loop mode initialization: circuit fault (overload / short circuit) after point
addressing or acquisition.
Check the electrical connections after the just addressed/acquired point.
8
Auto-addressed loop mode initialization: maximum number of points reached and lack of
voltage on LB.
The procedure completes correctly when a voltage is found on LB; warning: do not overcome
the limit of max 128 points per line.
10 Point too far from the circuit module cable too long or cable resistance too high).
11
Auto-addressed loop mode initialization: no answer from the point during the address
assignment phase.
Check the electrical connections after the point.
12
Auto-addressed loop mode initialization: point with random address not found.
Check the electrical connections.
13 Procedure stopped by the control panel (a stop command has been received).
20
Pre-configured loop mode initialization: line fault (overload or shortcircuit) at power on.
Check the electrical connections among the circuit module and the points connected directly
with LA and LB.
21
Pre-configured loop mode initialization: unexpected voltage on line LB.
A voltage on LB terminals has been detected at the beginning of the initialization procedure;
this voltage is probably due to an unwanted connection between line LA and line LB (please,
note that it is necessary to place at least one point in series between LA and LB).
23
Pre-configured loop mode initialization: missing answer in current from the point or open line.
The procedure completes correctly when a voltage on LB is detected.
27
Pre-configured loop mode initialization: line fault (overload / short circuit) after point addressing
or acquisition.
Check the electrical connections after the just addressed/acquired point.
28
Pre-configured loop mode initialization: maximum number of points reached and lack of voltage
on LB.
The procedure completes correctly when a voltage is found on LB; warning: do not overcome
the limit of max 128 points per circuit.
29
Pre-configured loop mode initialization: there is a point with invalid address.
The procedure only works with points having valid addresses (range 1 – 128).
40
Update loop mode initialization: line fault (overload or shortcircuit) at power on.
Check the electrical connections among the circuit line card and the points connected directly
with LA and LB.
41
Update loop mode initialization: unexpected voltage on line LB.
A voltage on LB terminals has been detected at the beginning of the initialization procedure; this
voltage is probably due to an unwanted connection between line LA and line LB (please, note
that it is necessary to place at least one point in series between LA and LB).
