Each digital output module uses one Modbus register for its data. The analog output
module requires two registers, one for each output channel. Therefore, a total of five
registers (registers 40001 through 40005) are needed to accommodate the four
output modules in the sample island bus assembly.
1 The value represented in register 40004 is in the range +10 to -10 V, with 11-bit resolution
plus a sign bit in bit 15.
2 The value represented in register 40005 is in the range +10 to -10 V, with 11-bit resolution
plus a sign bit in bit 15.
The digital modules use the LSBs to hold and display their output data. The analog
module uses the MSBs to hold and display its output data.
