5.5.3 Parameter value (PWE)
For each parameter, the transfer of the parameter value (PWE) is always as a word (16 Bit) or double word
(32 Bit). Only one parameter value can be transferred in a telegram.
A 32 bit parameter value comprises PWE1 (high value word) and PWE2 (low value word, 4th word).
A 16 Bit parameter value is transferred in PWE2. For negative values the high word must be set to FFFF
hex
.
Note: 32- Bit parameter values are only used with the posicon option. All the relevant parameters are
described in the supplementary posicon manual.
The parameter value is transferred as an integer value. For parameters with resolutions 0.1 or 0.01 the
parameter value must be multiplied by the inverse of the resolution.
Example: A start-up time of 99.99 seconds is to be set:
99.99s
→ 99.99 * 1/0,01 = 99,99 * 100 = 9999. Therefore the value 9999
dec
= 270F
hex
must be transferred.
