A rule engine instead of programming
IF-THEN rules replace ladder logic
Trigger conditions and actions are chosen from a form. There is no PLC program to write, and changing a rule needs no recompile or reflash — saving makes it live.
The same HRL as the ETH-A2E
The rule language is shared with the gateway, so one rule file works on both. The online HRL generator can also turn a plain-language description into rules.
Wide temperature, DIN rail
A −40 to 75 °C operating range with DIN rail mounting keeps outdoor enclosures and unconditioned plant rooms within scope.
Front-end control and communication
Sixteen DI/DO channels selectable as NPN or PNP, plus two 16-bit multi-function analog inputs. Communication covers Modbus TCP and Modbus RTU together with a CanBus industrial bus interface — vehicles, construction machinery and some drive equipment mostly run CAN, and having the interface on board removes the need for an external protocol converter. Supply is 24 V DC (10 – 27 V).
Wondering whether the rule engine can cover your control logic?
Describe the control sequence and signal list and we can help express the logic as HRL rules, and check whether the point count is sufficient.
