PLC Command Bridge
Sends vetted commands to line controllers, where a re-sent instruction is a safe no-op, never a double.
The PLC Command Bridge writes to programmable logic controllers over the protocols they already expose, typically Modbus TCP registers and coils or OPC UA writable nodes. Every writable target is declared up front with its type, bounds, and meaning; the connector will not touch an address it was not given. Commands are single-flight per controller and carry idempotency keys, so a network retry lands as the same instruction, not a second one.
This is deliberately the most conservative connector in the catalog. It never writes to safety systems, an out-of-bounds value is rejected before it leaves Fibric, and any doubt about controller state means the command does not run. Writes start propose-only available now and every command leaves a receipt with the target, the value, and the plan that proposed it. Built and maintained by Fibric, wired with a Fibric deployment engineer through the early-access program.

Authentication
Uses the security of the underlying path: network-layer scoping for Modbus TCP targets, X.509 certificate trust for OPC UA targets, plus Fibric's declared write allow-list.
What it reads
- Current values of the declared writable targets, read back before and after each command
- Controller reachability and mode, as a precondition for any write
- Command outcomes: applied, rejected, or timed out, per receipt
What it can do
- Write a declared register, coil, or node to a value within its bounds, propose-only to start
- Reset or acknowledge a declared flag as part of a vetted plan
Requirements
- IP reachability to each controller over Modbus TCP or OPC UA
- A declared write map: address, type, bounds, and meaning for every writable target
- Sign-off that no safety-instrumented targets are in scope
Works with
Exception RoutingOperator Clears the exception before it stalls the line, rerouting work and dispatching the fix the moment flow breaks on the floor. Available now Predictive MaintenanceOperator Hears the equipment going wrong before it fails. It reads vibration and runtime, predicts the fault, and opens the work order early. Available now Modbus TCPConnector Talks to the meters, drives, and PLCs that already run your plant, polling registers on a schedule and normalizing the readings. Available now OPC UAConnector The industrial standard for shop-floor data: browses the address space, subscribes to nodes, and keeps the model in sync. Available now SlackConnector Posts the proposed action, waits for the human confirm, then executes, all inside a channel that keeps the record.
