RS485 MODBUS Communications
DM3600 is available with RS485 serial communications using MODBUS RTU protocol, and can be used with
Status’ own M-Config software.
Physical Layer
4 wire or 2 wire half duplex RS485
Protocol
MODBUS RTU format
Breakdown Isolation
500 VAC
Maximum Fan out
32 units (can be increased with repeaters)
Termination Standard
RS485
The DM3600 is configured using the three keys on the front panel. The unit has two modes of operation:
The first is ‘Run’ mode. This will automatically be entered 5 s after power up. This is the principle mode
of operation. There are 6 possible key press combinations, as shown in the ‘Key Press Definitions’ diagram
below. The ‘Run Mode Options’ diagram shows the key presses required to access various states from the
run mode. (See diagram in Section 8.2 overleaf).
The other principle mode of operation is ‘Menu Mode’. The menu navigation method is shown diagrammatically
in the ‘General Menu Structure’ (see Section 9.1).
Once the menu mode has been accessed, the user can use the large ‘Menu Map’ (see Section 10.0) to
navigate through the menu structure.
All programming is done using the three front panel keys, A, B and C.
ESCAPE (A & B), ENTER (B & C) and CLEAR (A & C) are obtained by simultaneously pressing the two keys.
CYCLE (A), SHIFT (B) and INC (C) keys are pressed singularly.
