Notes on the control bits
SLOT This value is used to specify the loaded value for each channel. Use the LD_SLOT load re-
quest to evaluate the loaded value.
LD_SLOT This load request is used to specify the meaning of the SLOT (loaded value) value for each
channel. The user program performs the respective action, as soon as LD_SLOT changes.
When the loading request LD_SLOT = 011
B
is entered and the software gate is opened, each
counting operation begins with the start value. If another load request is entered and the soft-
ware gate is opened, counting continues with the current count at each start of the counting
operation. These two situations are also in effect when the hardware gate is configured and
the software gate is closed.
SW_GATE With this bit, you open and close the software gate of the respective channel. Together, the
software gate and the hardware gate form the internal gate. The module only counts if the
internal gate is open.
0 means: Software gate closed
1 means: Software gate open
RES_EVENT_UFLW Use this bit to initiate the resetting of the saved event in the EVENT_UFLW feedback bit for
RES_EVENT_OFLW Use this bit to initiate the resetting of the saved event in the EVENT_OFLW feedback bit for
RES_EVENT_CMP0 Use this bit to initiate the resetting of the saved event in the EVENT_CMP0 feedback bit for
RES_EVENT_CMP1 Use this bit to initiate the resetting of the saved event in the EVENT_CMP1 feedback bit for
the respective channel.
