7.8 APPENDIX 8 – PROCEDURE ERROR CODES
The table below reports the error codes returned by the circuit module after the failure of a procedure and the relevant
explanation.
Code Error
0
Auto-addressed loop mode initialization: line fault (overload or shortcircuit) at power on.
Check the electrical connections among the circuit line card and the devices connected directly with LA and LB.
1
Auto-addressed loop mode initialization: unexpected voltage on line LB.
A voltage on LB clamps 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
device 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 device or open line.
The procedure completes correctly when a voltage on LB is detected.
5
Auto-addressed loop mode initialization: missing answer from a device with invalid address.
The module could not communicate with the device: check the electrical connections.
6
Missing answer from a device with valid (1 – 128) address.
The module could not communicate with the device: check the electrical connections.
7
Auto-addressed loop mode initialization: line fault (overload / short circuit) after device addressing or acquisition.
Check the electrical connections after the just addressed/acquired device.
8
Auto-addressed loop mode initialization: maximum number of devices 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
devices per line.
10 Device too far from the line card (cable too long or cable resistance too high).
11
Auto-addressed loop mode initialization: no answer from the device during the address assignment phase.
Check the electrical connections after the device.
12
Auto-addressed loop mode initialization: device 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 line card and the devices connected directly with LA and LB.
21
Pre-configured loop mode initialization: unexpected voltage on line LB.
A voltage on LB clamps 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
device in series between LA and LB).
23
Pre-configured loop mode initialization: missing answer in current from the device 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 device addressing or acquisition.
Check the electrical connections after the just addressed/acquired device.
28
Pre-configured loop mode initialization: maximum number of devices 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
devices per line.
29
Pre-configured loop mode initialization: there is a device with invalid address.
The procedure only works with devices 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 devices connected
directly with LA and LB.
41
Update loop mode initialization: unexpected voltage on line LB.
A voltage on LB clamps 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
device in series between LA and LB).
42 Update loop mode initialization: lack of 4 consecutive addresses to assign to a multiple I/O module.
43
Update loop mode initialization: missing answer in current from the device or open line.
The procedure completes correctly when a voltage on LB is detected.
46
Update loop mode initialization: missing answer from a device with valid (1 – 128) address.
The module could not communicate with the device: check the electrical connections.
47
Update loop mode initialization: line fault (overload / short circuit) after device addressing or acquisition.
Check the electrical connections after the just addressed/acquired device.
48
Update loop mode initialization: maximum number of devices 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
devices per line.
49
Update loop mode initialization: the maximum number of addressed
devices
has been reached and there are
other
devices
not addressed yet on the line.
Warning: do not overcome the limit of max 128
devices
per line.
50
Update loop mode initialization: reached the maximum number of generated random addresses.
Repeat the procedure and/or manually address the
devices
not yet addressed.
