NOTE!
Mapping of invalid parameters or not available will return zero value.
The data is transmitted as an integer value, without the indication of the decimal places.
To obtain the network address (Net Id) of the parameters, refer to Appendix A.
6.1.2
Output Words
The SSW900 soft-starter has a writing area with 20 16-bit words available for cyclic data exchange of communication
networks. The data available in the write area (Output) is received from the network master. This area is shared
between the two Slots.
To map an object in the writing area, follow the steps below.
1. Configure parameter C8.1.2.1 (Slot 1) or C8.1.2.3 (Slot 2). Those parameters indicate which of the writing
words starts the output area for the specific Slot.
2. Configure on parameter C8.1.2.2 (Slot 1) or C8.1.2.4 (Slot 2) the quantity of reading words which must be
transmitted via network.
3. Parameters C8.1.2.6 to C8.1.2.25 enable to configure the data that must be provided on the writing words.
Those parameters must contain the network address (Net Id) of the data that must be transmitted on the
respective writing words. The Net Id list is available on the table A.2. Consider the size of each parameter
mentioned in list when programming each word.
Exemplo
The example below presents a configuration for Slot 1. Considering the following parameters to be mapped:
S5.2.5 Command Word Slot1.
S5.3.1 Value for Outputs DO Value.
S5.3.2.1 Value for AO AO in 10 bits.

Therefore, the configuration must be performed as shown below:
1. C8.1.2.1 Data Write Slot 1 1st Word = 1
→
first word transmitted via network is the word #1.
2. C8.1.2.2 Data Write Slot 1 Quantity = 3
→
sum of column “Qty mapped words”.
