BENSHAW RediStart RB2 User Manual

The control source must be serial for the starter to be started through Modbus. The Run/Stop bit must transition from 0 to 1 for a start to
occur. If the starter stops due to a fault, the action of the starter depends on the state of the AutoStart parameter (P66 – I/O19).
The fault reset bit must transition from 0 to 1 for a fault to be reset.
If any of the programmed digital inputs are programmed as Local/Remote inputs, then the local/Remote bit has no effect.
When the relays are programmed as “Off”, the relay bits may be written in order to control the relays. When the relays are programmed
for any function other than “Off” (Fault, Run, UTS for example), then the relay bits may be read to determine the state of the relays.
Starter Status Register:
Watts, VA, vars, and kW hour Registers:
Meter registers present 32 bit meters in two consecutive 16 bit registers. The least significant 16 bits are in the first register followed by
the most significant 16 bits in the second register.
Reading the least significant register latches data into the most significant register so that the data remains synchronized between the
two.
Starter Control Register
Parameter Registers
For those parameters that can be set either to "Off", or some value within a range (many of the protection parameters, for example) there
are two Modbus registers. One is an "enable" register, and the other sets the value within the range.
