Configuration and Calibration Registers MAO (Channel 19) MAI (Channel 20)
Register Parameter Parameter
211 Port 0 calibration IN_1 OUT_1
212 Port 1 calibration IN_2 OUT_2
213 Port 2 calibration IN_3 OUT_3
214 Port 3 calibration IN_4 OUT_4
215 Port 4 calibration IN_5 OUT_5
216 Port 5 calibration IN_6 OUT_6
217 Port 6 calibration IN_7 OUT_7
218 Port 7 calibration IN_8 OUT_8
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
