Feature bit
Number of the Feature bit: 0
Setting the startup characteristics
With this Feature bit you set the startup characteristics of the function blocks.
Note
This Feature Bit has no function in the "Out of service" operating mode. The process tag
remains in the "Out of service" operating mode after a warm restart of the CPU.
Note
The restart routines of the blocks reset the following outputs in OB100:
● Operating point outputs xx_AH_Act, xx_AL_Act, xx_WH_Act, and xx_WL_Act
This causes an outgoing message when initializing Alarm8_P in OB100 and an incoming
message after expiry of the RunUpCycle counter in the cyclic interrupt level.
Note
During a complete download with AS stop, the blocks (with Feature.Bit0 = 1) cannot
resume operation in their previous mode and control when restarted.
Setting the startup characteristics for the Mag6T block
Bit = 0: Starting the block in manual mode and in defined position. The totalizers are reset and
held ('Hold' command). Dosing is switched off (Stop command) if it is configured, and the
setpoint is set to internal.
Bit = 1: The block operates with the last valid commands before CPU-stop, stored at the Oldxxx
inputs, for the totalizers and the dosing unit. These inputs can be read back before a complete
download.
