The communication options that R. Stahl's customers have come to expect from their many HMI systems has now also been implemented for the most recent T-series widescreen devices. The 22’’ and 24’’ operator interfaces are now also available with built-in TCP/IP connectivity on request. This feature enables the devices to be used as flexible Thin Clients with TCP/IP connections to servers in the safe area. T-series HMIs use the RDP or VNC protocol for Thin Client communication with host computers directly over an Ethernet connection. Legacy solutions, i.e. connections via a KVM box within a KVM-over-IP setup, remain available as well. Up-to-date digital interfaces (DVI, USB) are supported in all cases. Consequently, a wide range of monitoring and operating options are available, including classic one-on-one allocation between hazardous area stations and PCs in the safe area, access from one single Remote HMI to alternating servers, or a set-up of multi-monitor field stations.
