How many industrial monitors (IFPs) can you connect to one SIMATIC IPC?

  • Entry
  • Associated product(s)
You can connect 1 to 3 monitors to a SIMATIC IPC. The maximum distance is limited by the transmission technology implemented and can be up to 100m.

An industrial monitor consists of an input unit with touch sensor and an output unit for image output. The following explanations always apply for the complete device - input unit and output unit.

Note
Only monitors of the same type are permitted to be connected to a SIMATIC IPC; for example, an IFP with multitouch screen and another IFP with multitouch screen, or a Panel PC with resistive touch screen and another IFP with resistive touch screen.

Table 3

Restriction in Windows Embedded 7 - WES7 E
If you are using the operating system "Windows Embedded 7 - WES7 E" together with a multitouch monitor, then the touch sensor of the monitor must be switched to single-touch mode. Refer to the following FAQ response for single-touch mode in Entry ID: 109475464.

If you connect two monitors, both monitors must be in single-touch mode. Only the "duplicated" setting is permissible in the operating system.

A third monitor can only be used for display. You cannot operate via a third monitor. Therefore its use is not permitted.

Table 4

Note
*1) The maximum number of all connected operator panels must not be exceeded.
*2) If IFP ETH monitors are connected via the ETH / LAN interface, then these monitors do not display any BIOS startup, blue screen messages or advanced start options. The reason for this is that an IFP ETH monitor can only display an image after the Ethernet driver has been enabled by Windows.

If BIOS startup, blue screen messages and advanced start options are to be displayed on an IFP ETH monitor, then the monitor has to be connected via the Display Port or the DVI interface on the IPC. For this you should follow the instructions of the operating manual, section 1.2  SIMATIC Industry PC Panel Drivers and Tools V1.2 PDT IFP ETH with capacitive multiple-touch screen.

To operate 3 IFP ETH monitors on IPCs that only have 2 Ethernet interfaces you need an additional switch with at least 4 ports.

Together with IFP ETH (100m distance) you can only operate two IFP ETH displays in Clone mode. The third IFP ETH display or the panel of a Panel PC can only be operated in Extended mode. All three displays cannot be operated simultaneously in Clone mode.

Connection of more than 3 operator panels
If you connect more than 3 operator panels to a SIMATIC IPC, undefined states might occur if there is a power failure or the network connection is interrupted with IFP ETHs. For example, an IFP ETH displays no image but the touch screen can be operated.

Using a multitouch operator panel in single-touch mode
You can operate an MT operator panel either in MT or ST mode. In ST mode all touch events are reported as mouse events to the operating system. The operator panel acts as if it were equipped with an ST operator unit.

Switching to ST mode is necessary with operating systems that do not support MT, WES7 E, for example. Use the "Switch Touch Mode" tool to switch modes. The tool is included in "Panel Driver & Tools" version V1.1 and higher, or as a download in Entry ID109752279.

Please note that only a maximum of two operator panels can be operated when using an MT operator panel in ST mode. More information about operating a SIMATIC IPC with two monitors is available in Entry ID109475464.

Note in the case of power failure of a component or if the cable is disconnected
If the cable connection between a SIMATIC IPC and the connected operator panels has been temporarily disconnected, then check the assignment of the main and 2nd monitors as well as the touch function. If necessary, restart the SIMATIC IPC to restore the function of the operator panels.

Connection cables for operator panels with up to 5m distance
Connection cables are available in lengths of 3m and 5m for direct connection of a SIMATIC IPC with an operator panel via the DP, DVI-I and USB.
