ERP-Gateway 12x Digital Input, 6x Digital Relay

  • ERP-Gateway 12xDigital Input, 6x Relay Output

ERP/PPS system controls digital relays - 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.

Background information

In addition to the standard functions of the Web-IO Digital, the ERP-Gateway 6x Relay also includes the patented Wayback procedure. As a platform- and operating system-neutral software interface, the Wayback procedure allows even communicatively limited systems to directly switch outputs - with no additional software packages, drivers or special access rights to the file system. The only prerequisite is the ability to open an FTP connection to the ERP Gateway. The desired command is sent as a user login followed by a password, whereupon the ERP Gateway switches the desired output - and that’s all there is to 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.
