Note
Input and Output parameters are the number of hardware registers that are connected to the I/O block. They define the
transducers to be used going to or from the physical world.
WARNING
Extreme caution must be used when writing port calibration values to registers 211 through 218. Only values read from
these registers shall be written to them. The purpose of these registers is to allow the network host to store the port
calibration values and then write them back to the actuator in case of replacement of the CPU module.
Note: The network host may write a Port Position Setpoint to Channel 3 (SP/OUT) as a 12-bit unsigned integer analog
value corresponding to 0% to 8% where the percentage relates to the port number 0 to 8. The analog value is
calculated as absolute value of Port Number / 100 * 4095. Example: Analog value for Port 6 = 6/100*4095=245.7 =
245. The actuator will accept the percentage analog value within a tolerance as shown below:
Port 0 =
0
If CA is configured as 1 for Home Port = 8,
Port 1 = 39 – 42
the MPA will accept either 0 or 327 for setpoint
Port 2 = 79 – 82
of Home Port. The acceptable range for Port 8
Port 3 = 120 – 123
is 325 to 329. (see page 21 for CA configuration)
Port 4 = 162 – 165
Port 5 = 203 – 206
Port 6 = 244 – 247
Port 7 = 284 – 288
