With LDMicro, the user can create programs in a ladder-diagram style in line with EN 61131-3.
In a ladder-diagram style, all elements of the program are arranged on horizontal lines (rungs).
The paths are always executed from left to right without an established rung order. This concept
has its origin in hard-wired relay circuits.
LDMicro offers a wide variety of applications:
•
Bit operations such as contacts, coils, setting/resetting
•
Edge detection
•
Time switches and enabling/disabling delays
•
Incrementing/decrementing/circulating counter
•
Arithmetic operations (16 bits, signed)
DCU programs that have been created with LDMicro can:
•
Use all inputs and outputs on the module
•
Respond to diagnostic events (short circuit, low voltage, etc.)
•
Communicate with a connected PLC
•
Release information about the network
File Types
Program files for LDMicro are named with .ld. These files can be loaded, edited and saved via
the LDMicro application.
To compile a DCU program for the DCU application, first select the correct destination type
under "
Settings -> Microcontroller -> Interpretable Bytecode
."
It is also possible to set the cycle time (Settings -> MCU parameters). A cycle time of 10 ms or
more is recommended.
