Table - Cyclic Data: Input buffer

Bytes |  | Slot | Name | Size [Bytes] | Data Type | Description | Default Range for scalable parameters
0 - 3 |  | 16 | Actual Pressure | 4 | SINT32 or FLOAT |  | 0 - 1’000’000
4 - 7 |  | 17 | Pressure Sensor 1 | 4 | SINT32 or FLOAT | In case of default valid range: Physical full scale value of the sensor (10 Volt) equals to 1’000’000. | 0 - 1’000’000
8 - 11 |  | 18 | Pressure Sensor 2 | 4 | SINT32 or FLOAT | Optional signal, only in case of two sensors. In case of default valid range: Physical full scale value of the sensor (10 Volt) corresponds to 1’000’000. | 0 - 1’000’000
12 - 15 |  | 19 | Actual Position | 4 | SINT32 or FLOAT | Maximal value in the range = Valve is open Minimal value in the range = Valve is closed* *Valid for valves without isolation function | 0 - 100’000
16 - 19 |  | 20 | Actual Target Position | 4 | SINT32 or FLOAT |  | 0 - 100’000
20 |  | 21 | Control Mode | 1 | UINT | 0 = Init 1 = Homing 2 = Position 3 = Close 4 = Open 5 = Pressure Control 6 = Hold | 7 = Learn 8 = Interlock Open, 9 = Interlock Close 10 = Maintenance 12 = Power Failure 13 = Safety 14 = Error | Not scalable
21 - 22 |  | 22 | Error Number | 2 | UINT16 | 20 = no stop detected during homing 21 = valve blocked during homing 22 = valve blocked 40 = motor driver fault | Not scalable
