Input Filtering (Hardware Setting); Assignment Of Digital Output Dq.0, Dq.1, Dq.2, Dq.3 - Siemens SIWAREX WP251 Manual

8.8.3

Input filtering (hardware setting)

To ensure that the inputs do not respond too quickly to the signal change, a minimum signal
pending time can be specified. The pending signal is not processed further until this time has
elapsed.
The following values can be set:
Value
0
1
2
3
8.8.4

Assignment of digital output DQ.0, DQ.1, DQ.2, DQ.3

A status display can be assigned to a digital input. This is done on the basis of the bit
number.
Assignment for output 0, 1, 2, 3:
Function code
(decimal)
0 ... 63
64
65
100 ...163
255 (default)
1000-1015
1100-1115
2000-2031
2100-2131
3000-3031
For a single component scale, three of the outputs are typically linked directly to the "Coarse
signal" (function code 41), "Fine signal" (function code 42), and "Empty" (function code 43)
status bits in order to directly control the corresponding dosing elements or the associated
relays of SIWAREX WP251.
