Programming the PLC requires a PC with ISaGRAF
®
The ISaGRAF software enables you to program a control system that is tailored to the specific
needs of your plant (ISaGRAF
low the structures and rules stipulated in IEC 61131-3. The PLC may be programmed with the
languages defined in the standard: Sequential Function Chart (SFC), Instruction List (IL), Flow
Chart (FC), Function Block Diagram (FBD), Ladder Diagram (LD), and Structured Text (ST).
There are 128 KB of memory available in the PLC for the ISaGRAF
The application is complied to machine code in the PC environment. This code is then trans-
ferred to the PLC over the front RJ-45 jack (connecting cable 1400-7620).
Programming languages:
Sequential Function Chart
(SFC):
Instruction List (IL):
Flow Chart (FC):
Function Block Diagram
(FBD):
Ladder Diagram (LD):
Structured Text (ST):
For operation and application of the ISaGRAF
cluded in the software package. To enable simple and clear programming, ready-made func-
tions and function blocks, e.g. for boiler systems, heat exchanger sequence control, ventilation
systems, heating circuits or domestic hot water systems, are available from SAMSON.
