in case paramArray = 0 [PARAMS_CONFIG] the data signals has the below described meaning
Master
broad
cast
l_u8_rd_data0
the signal is interpreted according to
the l_u8_rd_paramArray signal
(paramArray = 0)
node ID
. This signal changes current
Stepper Controller node ID to this
new node ID.
Caution: Beginning the next
configuration frames. the configured
node will react only when the signal
l_u8_rd_nodeID = this new node ID
<0,0xF

<0,255>
l_u8_rd_data1
the signal is interpreted according to
the l_u8_rd_paramArray signal
(paramArray = 0)
