FB details
This FB selects the system operation mode, such as manual, automatic, and semi-automatic. The default state is changed to
the ModeChanged state (8005H), where all o_bS_ModeXSel and o_bS_AnyModeSel are OFF, after the activation of the FB.
For the transition from the ModeChanged to ModeSelected state, the following conditions are required.
• i_bAutoSetMode=OFF
When i_bS_SetMode is set to ON, the new i_bS_ModeX input leads to an o_bS_ModeXSel output.
• i_bAutoSetMode=ON
The new i_bS_ModeX input automatically leads to a new o_bS_ModeXSel output.
The transition from the ModeChanged to ModeSelected state is only valid, if one i_bS_ModeX is ON. In addition, the
transition from one i_bS_ModeX input (only one i_bS_ModeX from i_bS_Mode0 to i_bS_Mode7 is ON) to ModeSelected state
(8000H) is not monitored by a timer.
If the FB is in the ModeSelected state, the simultaneously occurrence of a new i_bS_ModeX input (higher priority) and the
OFF i_bS_Unlock signal (lower priority) leads to the ModeChanged state.
The i_bS_ModeX input parameters, which are not used for mode selection, should be called with the default value OFF to
simplify program verification. i_bAutoSetMode input shall only be activated if it is ensured that no hazardous situation can
occur when the safety programmable controller is started.
(14) i_bReset Bit OFF Reset input.
