Configuration with the ADAM Command Set

ADAM systems can also be configured by issuing direct command from within the terminal emulation program that is included with the ADAM utility software.

The following example guides you through the setup of an analog input module. Assume that an ADAM-5018 Thermocouple Input module in slot 1 on an ADAM-5000/485 system still has its default settings (baud rate 9600 and address 01h). The system is first request- ed to send its default settings and then reconfigured.

Note: An analog input module requires a maximum of 7 seconds to perform auto calibration and ranging after it is rebooted or powered on. During this time span, the module cannot be addressed to perform any other actions.

Example:

Make sure that the module is properly connected as shown in Chapter 4, Figure 4-3. Power up all the connected devices, start the terminal emulation program, and issue the following command:

$01S1B(cr)

This command requests the module in slot 1 of the ADAM-5000 system at address 01h to send its configuration status

!010500

The module of the system at address 01h responds that it is config- ured for an input range of ±2.5 V, integration time of 50 ms (60 Hz), format = engineering units and no checksum checking or generation.

To change the configuration setting of the analog input module, the following command is issued:

$01S1A0F00(cr)

$ = change configuration

01 = target module at address 01
