06 / Overview
About Siemens PLC Repair & Programming
We repair and re-commission the full SIMATIC range — from LOGO! and S7-1200 on packaging machines up to S7-400 and ET200 racks on process plant. The commonest calls are a CPU sitting in STOP with a diagnostic-buffer entry, a BF light from a Profibus/Profinet segment fault, or corrupted retentive data after a backup-battery failure on legacy S7-300.
We upload and preserve your STEP 7 / TIA Portal project first (uploading from a running S7-300/400 where no offline copy exists), document the logic, and hand back a commented, backed-up project — so a machine only one person understood becomes one your whole team can support.
