ERP-Gateway
2x Digital Input, 2x Digital Output PoE

  • ERP-Gateway 2x2 Wayback

ERP/PPS system controls digital in-/outputs - simply, using the FTP user name

Use your system to open a standard FTP connection to the ERP Gateway and send the control command as a login name. After authenticating by the password, the output is immediately turned on or off.

Worth knowing

Patented Wayback feature:
In addition to all the standard functions of the Web-IO® Digital, the ERP-Gateway 2x Digital PoE also includes the patented Wayback procedure. As a platform- and operating system-neutral software interface, the Wayback procedure enables even communication limited systems to directly switch outputs - without any additional software packages, drivers or special access rights to the file system. The only prerequisite is the ability to establish an FTP connection to the ERP gateway. The desired command is sent as the user login followed by a password, whereupon the ERP gateway switches the desired output - that’s it!

ERP/PPS systems such as SAP, Baan, PSI etc. can in this way, using a simple FTP login, send switching pulses to machines, PLCs or any other desired outputs without actual data transmission.

SAP application example
When a certain production quantity is reached, you need to use the SAP system to switch a light column to red. Without any additional, expensive software components a small ABAP procedure opens the FTP connection to the ERP Gateway when the event occurs and sends the command as a user login, whereupon the signal column is immediately switched to red.

Possible applications
Remote monitoring, automation technology, home and building technology and building visualization, process monitoring, photoelectric beam control, gate control, light barrier control, machine data acquisition, customer counting, fault indicators and much more.
