4.4 Identifier commands
4.4.1. Placing a device-specific identifier within the network „A“ (41h)
This command is for creating an automated process for defining successively the device identifier of each indi-
vidual N 155 upon commissioning of the equipment. The first device identifier to be placed is given by broadcast
command to all networked N 155 as follows:
SOH Adr Cmd address = 01 EOT CRC
send
01h 83h 41h 30h 31h 04h B4h
All N 155 will now show the identifier to be set which has just been sent in the upper line of the display. The
lower line will indicate the device-specific identifier. Push key provided at N 155 to enter the new identifier. The
identifier is entered and indicated in the lower line of the display (as new device identifier). Both identifiers are
now identical. After 3 seconds N 155 will send the following confirmation „B“ (42h) to the master:
SOH Adr Cmd address = 01 EOT CRC Send to
Master 01h 21h 42h 30h 31h 04h 86h
The Master now is able to give command „A“ with the next identifier to be placed as previously described.
This way, all N 155 in the network are automatically given the specific identifier (in successive order).
Important: The confirmation command „B“ sent by N 155 to the master will be repeated after 3 seconds in case
the master is not giving the „A“ command again.
Show identifier in the display „A“ (41h)
This command as broadcast command (Adr = 99) without any parameters will make each N 155 in the network
indicating the device-specific identifier in the bottom line of the display. The upper line is blind.
This command is a designated broadcast command.
SOH Adr Cmd EOT CRC
Send
01h 83h 41h 04h 80h
Response no confirmation
N 155 remains in this mode until being switched off and on again or receiving another command except „A“, „R“,
„t“ or „u“.
If this command without any parameters is sent to a valid device identifier (except 99), the target display will
return to standard operation mode. The presently valid device identifier will be replied.
SOH Adr Cmd EOT CRC
Send
01h 21h 41h 04h 0Ah
SOH Adr Cmd Adr=01 EOT CRC
Response
01h 21h 41h 30h 31h 04h 9Eh
Extended identifier command „AX“ (41h,58h)
This command is for placing the individual N 155 device identifiers in a way as previously described.
The identifier to be given is sent to all N 155 in the network by the following broadcast command:
SOH Adr Cmd Cmd2 address = 01 EOT CRC
Send
01h 83h 41h 58h 30h 31h 04h 40h
Similar to the standard command, the upper line of the N 155 display will show the identifier to be placed that
has just been sent. Also entering the identifier will be the same.
However, in this case NO identifier confirmation command „B“ is returned. Whether the identifier has been en-
tered or not has to be checked by master, for example by “R” command (read current value). The “R” command
is sent to the N 155 with corresponding identifier. If the identifier is entered, the target display will reply and the
master can pass on to the next identifier. Regarding other commands the N 155 display will switch to standard
operation.
