Section 4: Input and Output Data
Section 4: Description of the Input
and Output Data
General information: Depending on the master, it is possible that the low byte (bit 0 - 7)
and the high byte (bit 8 - 15) might have to be swapped. The transmission mode
(big endian/little endian) always has to be adjusted such that the analogue values are
transmitted correctly. Only then can the binary data be swapped.
4.1 Modules for the Input Data
(Data from Master to Slave)
4.1.1 Command
Module number: 23
Hex
ID-byte: 60
Hex
(1 word AA / consistency 1 word)
Data format: 16 bit (bit field)
Structure:
Table 3.
Bit no. Function
Description
Bit = 0 Bit = 1
0 OPEN - OPEN command in REMOTE mode.
1 CLOSE - CLOSE command in REMOTE mode.
2 STOP - STOP command in REMOTE mode.
3 EMERGENCY - OPEN - EMERGENCY - OPEN command in REMOTE & LOCAL modes.
4 EMERGENCY - CLOSE - EMERGENCY - CLOSE command in REMOTE & LOCAL modes.
5 BLOCK -
BLOCK actuator in LOCAL & REMOTE modes
The actuator is not operable either via the selector switch locally
nor via commands by REMOTE nor PROFIBUS.
6 POSITIONER OFF - Deactivating the positioner in REMOTE mode.
7 WATCHDOG
Toggle bit from the master for bus watchdog monitoring With bus watchdog
time set, the bit has to toggle within this time; otherwise there is a bus error.
8 OPEN SH -
OPEN command with self-retention in REMOTE mode,
jettison with STOP.
9 CLOSE SH -
CLOSE command with self-retention in REMOTE mode,
jettison with STOP.
10 LOCK - OPEN -
Trigger locking OPEN (in LOCAL and REMOTE modes)
The actuator runs OPEN with highest priority, the command
continues to queue internally even after reaching the OPEN end
position. Jettison only with LOCKING OFF, supply off or OFF mode.
11 LOCK - CLOSE -
Trigger locking CLOSED (in LOCAL and REMOTE modes)
The actuator runs CLOSED with highest priority, the command
continues to queue internally even after reaching the CLOSED end
position. Jettison only with LOCKING OFF, supply off or OFF mode.
12 LOCK - OFF - Jettison locking
13 BLOCK LOCAL -
BLOCK actuator in LOCAL mode
The actuator is not operable via the selector switch locally.
14 FAILSAFE - Trigger the failsafe unit (provided there is one).
15 OVERRIDE - Binary inputs are not processed.
