Independent Controls Engineer — United Kingdom
TMH Automation Ltd
PLC and HMI programs for machine and line controls — written in Siemens TIA Portal or Rockwell Studio 5000, and handed over with FAT/SAT documentation your quality team can actually execute.
01 Scope of Work
5 SERVICE LINESWhat gets delivered, specifically — not a list of capabilities, a list of outputs.
PLC & HMI Programming
Ladder, structured text and function block programs for Siemens S7-1200/1500 (TIA Portal) and Rockwell ControlLogix/CompactLogix (Studio 5000), with HMI screens built in WinCC Unified or FactoryTalk View.
Machine & Line Automation
Control philosophy, I/O architecture and sequence logic for standalone machines and multi-station lines — from electrical handoff through to commissioning and ramp-up.
Robotic Integration
PLC-to-robot handshaking, safety interlocking and cycle synchronisation for robot cells running alongside conveyor, indexing and process equipment.
Vision System Integration
Keyence and Cognex vision jobs — part presence, print and date-code verification, pass/fail gating — wired into PLC logic as a clean discrete signal, not a black box.
Validation Documentation
URS, FDS, FAT and SAT documents written to be executed, not filed — traceable test steps that hold up under GMP and ISO-regulated audit.
02 Technical Expertise
Platform-agnostic by design — fluent across both major industrial control ecosystems, not tied to one vendor.
Siemens
Rockwell
Motion Control
Electronic gearing and camming on servo axes — master/slave ratios, cam profile editors and registration moves for indexing, flying shears and pick-and-place synced to line speed.
Machine Vision
Keyence and Cognex vision systems for inspection, verification and part-presence checking.
Regulated Environments
Documentation and change control practices suited to GMP and validated manufacturing.
03 PackML
A common state language for machines and lines — used so equipment from different vendors reports status the same way.
PackML (ISA-TR88.00.02) is the industry-standard state model for packaging and processing machines. Instead of every machine reporting status in its own bespoke way, PackML defines a common set of operating states — so a filler, a labeller and a case packer from three different OEMs all describe "running," "stopped" and "faulted" the same way.
-
→
Consistent machine states across multi-vendor lines, so operators, SCADA and MES all read the same status language.
-
→
Faster integration and commissioning when adding, replacing or swapping machines within an existing line.
-
→
Accurate, comparable OEE and downtime reporting without bespoke state-mapping for every machine.
-
→
Cleaner line-level orchestration — upstream and downstream equipment can react predictably to a shared state model.
Waiting state (holds until commanded) Acting state (auto-advances)
