Chapter 1: Getting Started
Q. Which devices can I connect to the communication ports of the DL05?
A. Port 1:
The port is RS-232, fixed at 9600 baud, and uses the proprietary K-sequence
protocol. The DL05 can also connect to Modbus RTU and
Direct
NET networks as a slave
device through port 1. The port communicates with the following devices:
• Direct
SOFT (running on a personal computer)
• D2-HPP handheld programmer
• Other devices which communicate via K-sequence protocol should work with the DL05
Micro PLC. Contact the vendor for details.
A. Port 2:
The port is RS232, with selective baud rates (300-38,400bps), address and parity. It
also supports the proprietary K-sequence protocol as well as
Direct
NET and Modbus RTU
and non-sequence/print protocols.
Q. Can the DL05 accept 5VDC inputs?
A
. No, 5 volts is lower than the DC input ON threshold. However, many TTL logic circuits
can drive the inputs if they are wired as open collector (sinking) inputs. See Chapter 2 for
I/O wiring guidelines.
