Thread Starter

Hello, I hope Someone can help,

Holzma Panel Saw.

We have a Homatic Controller in our Holzma Saw. Date 1990. Power supply in slot 1 NT 40, CPU slot 2 CP 60 program # 7318cad2 05.01.95. the next 4 slots have a name of MAESTRO, MGC1, MARC, Mm2m. then we have to encoder readouts PNC1, PNC1, next inputs E243, E243 Then outputs A163,A163.

We need to fine out who makes the controller and what we need to download ladder program. Or get a copy the ladder logic for this model saw. We do
not have a copy of the ladder program and waste so much time troubleshooting the saw.

You should directly contact Holzma-Machines in Germany to get an readout of the machine-program, or to get help with your problems.

Best regards
Hello kevin,

I have several Holzma saws and have used the B & R software.

B & R stands for Bernecker & Rainer.

The software for the PLC you mention is MSDOS Based.

On "our" saws there is a monitor for entering cutting patterns also there is a "Status" check screen for checking the status of Inputs/Outputs/Markers/Timers etc.

Talk with Holzma in germany and request a print out of the ladder diagram.
... these saws are a pain without the understanding of the logic...

-Holzma Converter for laptop to PLC
B&R Model # BRKAOL5-1
-Software to view/modify logic
B&R Model # Swpic-3

Order from B&R Industrial Automation Corp.
