how to set analog outptut in plc t100md+1616?
i try to use this program :
SETDAC 1,2048
that program should give current output 10 mA, but when i use multimeter to measure the current output between D/A #1 and GND, there are nothing measured current.

Did you connect the analog power supply to the 12-24V DCIN and AGND pin? This is required on T100MD1616+ to power the analog circuitry.

yes,.i have same problem with you guys
i have connect the 14 Vdc to Power supply I/O and Gnd, but when i measure the output current between D/A #1, i get nothing
please help me

Hi guys. Please try to check if you have tested the correct pins for the analogue output. Documentation need some time to study. I was having the same problem with 888 in the first place. Found out I'm measuring the wrong pin for the voltage in the end.

T100MD1616+ requires seperate power supply inputs to its analog power supply input, otherwise the analog circuitry has no power to drive the output or measure the inputs. So please check your power supply connection. Please refer to the installation guide for the wiring requirement.
