ABB ARC GUARD SYSTEM™ – TVOC-2-COM MODBUS CONFIGUR ATION MANUAL 27
4.4.3.4
Error x DTC, number y and z
A diagnostic trouble code (DTC) consist of 6 numbers.
When displayed on the HMI it has the following format:
n6-n5-n4-n3-n2-n1, where n<n> denotes number n.
Example: With DTC 64-0-0-2-0-0, number 3 has value 2 and
number 6 has value 64.
Two numbers are stored in each register, the first number
(y) in the most significant byte and the second (z) in the
least significant.
4.4.3.5
Number of errors
The number of errors that has occurred.
4.4.4 Custom name registers
The custom name registers contains the letters in the
custom name that can be programmed to the HMI.
Allowed characters are the alphanumeric characters plus
“-“, “_” and “ “ (space). This means ASCII character 32, 45,
48-57, 65-90, 95, 97-122. If not all 16 characters are needed,
the trailing characters should be set to value 32 (space) to
keep the layout of the name center aligned.
In each register, two characters are stored. One in the
most significant byte and one in the least significant.
Example:
To set the custom name to “Example” the
registers should be set as follows
Custom name, letter 1 and 2
0x4578 (Ex)
Custom name, letter 3 and 4 0x616D (am)
Custom name, letter 5 and 6 0x706C (pl)
Custom name, letter 7 and 8 0x6520 (e )
Custom name, letter 9 and 10 0x2020 ( )
Custom name, letter 11 and 12 0x2020 ( )
Custom name, letter 13 and 14 0x2020 ( )
Custom name, letter 15 and 16 0x2020 ( )
Using modpoll (see 5.2 Example of reading with modpoll
below) the command is:
modpoll -m rtu -a 247 -0 -r 400 COM1 0x4578 0x616D 0x706C 0x6520 0x2020 0x2020 0x2020 0x2020
