Industrial Automation
PLC programs for MDR conveyors, VFDs, sorters, and scanners — logic that keeps product moving predictably.
Why we do this
Conveyor systems fail quietly when interlocks, sequences, and fault handling are incomplete — especially on MDR zones, VFD-driven sections, and sorter divert points. Clear PLC logic protects throughput and makes recovery faster.
We write and structure programs so operators, electricians, and future engineers can understand how the line behaves under normal and fault conditions, including how photoeyes, scanners, and drive faults feed into modes and alarms.
How we do this
Reliable PLC logic for MDR, conventional conveyors, VFDs, sorters, and scanner-driven decisions.
Map zones, photoeyes, MDR rollers or motors, VFDs, scanners, and handshakes before writing code.
Use consistent patterns for modes, faults, and sequences so logic stays maintainable.
Safety and process interlocks are explicit, testable, and documented.
Programs are written to support stepwise bring-up, not just a final “it runs” demo.
HMI and status messaging — jam, divert miss, scanner no-read, VFD fault — help people diagnose issues without guessing.
What we do
Representative ways we can help. Exact scope is defined with you for each engagement.
Motor driven roller (MDR) and conventional conveyor sequences — accumulation, release, divert, and coordinated multi-zone motion.
Sort/divert decisions tied to scanner reads, photoeyes, and destination routing — with clear no-read and recirculation paths.
Variable frequency drive start/stop, speed references, and fault handling wired into PLC modes and interlocks.
New programs or cleanup of existing logic for clarity and reliability across zones and equipment.
Alarm strategies and safe recovery paths that reduce scramble during jams, drive faults, and scanner misses.
Coordination with photoeyes, safety circuits, remote I/O, and upstream/downstream equipment over industrial networks where needed.
Standards
Conveyor and sorter logic has to be maintainable under shift pressure. We program to common PLC language standards, machine electrical safety expectations, and clear tagging so your team can diagnose stops without guessing.
The international standard for PLC programming languages (ladder, structured text, function blocks, and more) — the shared grammar of industrial control code.
How we follow it: We write structured, modular programs in the languages your platform supports, with consistent naming and organization so another engineer can pick up the work.
Batch and enterprise-integration models that help separate equipment modules, recipes, and higher-level production context when lines talk to MES or batch systems.
How we follow it: Where batch or MES interfaces matter, we keep equipment modules and state models clear so PLC logic maps cleanly to higher-level systems without tangled tags.
Machinery electrical practices that expect defined e-stops, guarding interlocks, and controlled restart behavior.
How we follow it: We program interlocks and restart sequences deliberately, document safe states, and keep safety-related signals visible in the code and HMI — not buried in side effects.
Tag naming, comments, and sequence documentation are what make conveyor logic serviceable after the original programmer leaves.
How we follow it: We apply consistent tag schemes, sequence charts, and change notes so MDR zones, VFDs, scanners, and divert logic stay understandable.
Share your MDR/conveyor layout, sorter or scanner needs, and VFD constraints — we can discuss a maintainable programming approach.
