Signal sequence of acknowledgement controlled setpoint transfer
Description:
The block transfers the pending setting values from the user when a
rising edge is detected on the SPV_RIE signal (from 0 to 1).
Checkback signal SPV_RIE_ACKN = 1
Acknowledges the transfer of the setpoints from the positioner in the
form of a checkback signal for the user
With control signal SPV_RIE
acknowledge transfer is confirmed by the user
Checkback signal SPV_RIE_ACKN = 0
as conclusion of setpoint transfer
This input is low active and is connected to logical 1 in the factory
setting as an auxiliary input. All outputs of the basic positioner (i.e.
binectors and connectors) of the set/setpoint transfer are set to zero
with logical "0" (KK0874, KK0875, K0872, K0873, B0874, B0875,
B0876 = 0) as is the case after Power ON.
This gives the user the option to delete the valid outputs.
An abrupt compensating movement of the axis may occur if the RESET
signal is output without precautionary measures having been taken.
