Const
Registers one FC16 (write multiple registers) transaction can carry.
The limit follows from the PDU: 253 bytes, less the function code, the starting address, the quantity, and the byte count, leaves 246 bytes of payload.
Many devices stop at a lower number than the specification allows. Pass PlanWritesOptions.maxRegistersPerWrite when the device says so.
