01 / The work

What plc programming actually involves

PLC work splits into two very different jobs: recovering a controller that has stopped, and changing logic on one that runs. Both need the existing program backed up before anything is touched — an undocumented change on a machine with no backup is how a short stoppage becomes a long one.

We work on ladder, function block and structured text across the common industrial platforms, and we leave the site with the program archived and the changes written down.

02 / Scope

PLC Programming on site

Fault Diagnosis

Diagnostic buffer analysis, scan-time and watchdog faults, I/O module and fieldbus failures traced to the failing node.

Logic Development

New sequences, machine modifications and safety interlock changes, written to be readable by the next engineer.

Backup & Documentation

Program archives, I/O lists and change records handed over so the plant is not dependent on one person's memory.

03 / Common faults

Questions we get asked on site

The faults that bring us out most often, and what gets checked first.

Why has the PLC dropped into STOP mode?+

Read the diagnostic buffer first — it usually names the cause directly. Common entries are a scan-time watchdog overrun, an addressing error reaching a module that is absent or failed, a battery-backed memory loss, or a fieldbus node that dropped and took the rack with it.

An input or output channel is dead. Is the module faulty?+

Not necessarily. Field wiring, a failed sensor, or a shorted 24V supply that has tripped the module's protection all present as a dead channel. Force the channel from the software first: if the module responds, the fault is downstream in the field.

Can logic be changed without stopping production?+

On many platforms yes, through an online edit — but only with a verified backup in hand and a tested rollback. Whether it is advisable depends on what the change touches; anything affecting a safety interlock is done with the machine stopped.
