Signals Of Dcs 500 - ABB DCS 500B Description

Signals of DCS 500

DCS/DCF500B signals are divided to several different signal groups. Signals of a certain group
belong to the same functional part of the control program. Maximum number of signals in one
group is 99.
Every signal is described using the same structure, which is shown by their basics below:
Name
Signal of {standard function block} function block
Explanation
index data type
Name is given in the same format as it is seen on the panel.
Sig mentiones the name of the function block using this signal; at the end of this
line the page of the software diagrams available at the end of the System
Description is given; at some signals the software version is named this
signal is available for the first time
Expl description in verbal form
Index of a signal contains a group number and an element number. Last two digits
are the element number and other numbers before them form the group
number:
10101
11401
Data type is given with a short code:
FB_O:
S:
I2
E2
PB
B
U2
Scaling factor see table for parameters
Maximum values are given as internal values for those signals which can be modified
by user.
Minimum values are given as internal values for those signals which can be modified
by user.
Default not used for signals
Unit is given for signals which have an unit.
Example: The signal which is giving the actual motor voltage has following description:
U_ARM_ACT
Signal of SETTINGS-function block.
Actual voltage of the motor. Scaling based on signal U_NET_DC_NOM
10505 FB_O: I2
Name U_ARM_ACT
Sig will be found at the SETTINGS function block, which is shown on the
software diagrams on page 2 out of 16
Expl description in verbal form
Index signal group = 105, element = 05
Data type FB_O:
I2
Scaling factor as for VOLT
Maximum not available
Minimum not available
Default not available
Unit is Volt;
scal. factor maximum
=> signal group = 101, element = 01
=> signal group = 114, element = 01.
