Communication
7–6
The DTAM Micro supports two operating systems.
•
Communication with a PLC-5 requires PLC5-DF1 protocol
•
Communication with an SLC requires AB DH-485 protocol
•
Communication with a MicroLogix 1000 requires PLC5-DF1 protocol
The RS-485 and RS-232 versions of the DTAM Micro support both systems:

➀ The DTAM Micro RS-485 port supports RS-422 communication with the PLC-5. RS-422
communication is limited by the PLC to 19.2K baud and a distance of 200 feet (61 meters).
The operating system is selected when an application is created.
Applications are downloaded with the applicable operating system. If you
download an application that has a different operating system than the
current operating system in the DTAM Micro, you are prompted to download
the new operating system. Refer to Chapter 4 for additional information.
Communications Parameters
The communication settings of the DTAM Micro must be set to match the
SLC, PLC, or DH-485 network. The following parameters can be set for
both the RS-232 and DH-485 communications port.
Parameter Selections
Baud Rate 300, 1200, 2400, 4800, 9600, 19200, 38400
