Sequence for the HT 8
Procedure:
1. Connect HT 8 to a connection module and calibrate the touch screen.
Additional softkeys are available for convenient touch panel operation:
– "OK" has the same effect as the <INPUT> key
– Select "DEF" to save the "Default" settings.
– "Edit" has the same effect as the <F10> or <MENU SELECT> key.
2. Select HT 8 Individual Mode:
According to the default setting for an HT 8, "HT 8 Individual Mode" is deselected with "No".
This means "Auto" mode is activated for automatic detection in the system network. The
HT 8 is automatically detected based on its name "DIP_". If "HT 8 Individual Mode" is
activated with "Yes", the HT 8 is identified by its MAC address on the system network.
3. For an HT 8, confirm the "DIP..." name proposed by the system or adapt the name. You
can select any other characters.
Press the <INPUT> key to apply the following values as default settings for the HT 8:
The following message will then appear: "New TCU 'DIP10' registered."
Note
The TCU index is used to evaluate the direct keys. Direct keys can only be activated by
appropriate devices. For an HT 8 the TCU index cannot be set, but is assigned by the
system.
Activate direct keys
The signals from pressing the direct keys are sent directly to the PLC. In the PLC, the keys
appear as 16 digital inputs.
Additional information on programming the PLC is provided in:
