More process inputs and more functionality have been added to ABB's SM500F field-mountable videographic recorder.
 Seven inputs are now available (up from four), matched by 12 software recording channels (up from eight), enabling plant engineers to gain a more detailed process overview.
Also, each of those channels can record process and communications inputs, math block results, digital signals and other values.
Add to that new RS485 Modbus communications, and the SM500F is now much better for OEMs producing equipment such as autoclaves, sterilisers and retorts, with PLC control. Incidentally, the RS485 module has two more digital inputs, further expanding the SM500F's I/O capability.
As for functionality improvements, everything from batch numbers and information can be tagged to process data records, with data entered via the front panel or automatically, via Modbus, providing further integration with PLCs and control systems.
And for steriliser, autoclave and retort applications, the SM500F now incorporates the efficiency-boosting F0 calculation on each recording channel. When compared to time-based systems, F0 enables a sterilizer operator to reduce the cycle time, boosting efficiency while still ensuring appropriate sterilisation levels.
