Configurable logic blocks
The configurable logic blocks are available in two categories:
•
Configurable logic blocks that do not propagate the time stamp and the quality of signals.
They do not have the suffix QT at the end of their function block name, for example,
SRMEMORY. These logic blocks are also available as part of an extension logic package
with the same number of instances.
•
Configurable logic blocks that propagate the time stamp and the quality of signals. They
have the suffix QT at the end of their function block name, for example, SRMEMORYQT.
13.5.1
Application
A set of standard logic blocks, like AND, OR etc, and timers are available for adapting the IED
configuration to the specific application needs. Additional logic blocks that, beside the normal
logical function, have the capability to propagate timestamp and quality are also available.
Those blocks have a designation including the letters QT, like ANDQT, ORQT etc.
13.5.2
Setting guidelines
There are no settings for AND gates, OR gates, inverters or XOR gates as well as, for ANDQT
gates, ORQT gates or XORQT gates.
For normal On/Off delay and pulse timers the time delays and pulse lengths are set from the
local HMI or via the PST tool.
Both timers in the same logic block (the one delayed on pick-up and the one delayed on drop-
out) always have a common setting value.
For controllable gates, settable timers and SR flip-flops with memory, the setting parameters
are accessible via the local HMI or via the PST tool.
13.5.2.1
Configuration
Logic is configured using the ACT configuration tool in PCM600.
Execution of functions as defined by the configurable logic blocks runs according to a fixed
sequence with different cycle times.
For each cycle time, the function block is given an serial execution number. This is shown when
using the ACT configuration tool with the designation of the function block and the cycle time,
see example below.
