Advantech RS-485 user manual ADAM-5056D Digital Output during Power-on and Reset

I/O Modules

Main Units Supporting Digital Output Holding Function

The Digital Output Holding Function is applicable only to ADAM- 5510 and ADAM-5511. Other main units, such as ADAM-5000/485, ADAM-5000/CAN and ADAM-5000E, do not support this function, since their firmwares will automatically clear the digital output.

Although the firmware of ADAM-5510 and ADAM-5511 will not automatically clear the digital output value, it is nevertheless left as user's free choice to write a program either to clear the digital output or to set the initial value for the system.

The digital output behaviors during power-on and reset are summa- rized in the following table:
