environment. The ModbusTCP protocol takes the Modbus instruction set and wraps TCP/IP around
it.

PROFIBUS DP
The IND560x Terminal communicates to a PROFIBUS-DP master according to DIN 19 245. The
PROFIBUS option consists of software that resides in the IND560x Terminal and a printed circuit
board that installs in the ACM500 communication module to implement the data exchange.

ARM100 Module

The ARM100 Remote Discrete I/O Module is designed to extend the control network of METTLER
TOLEDO industrial terminals. This high performance module provides four inputs and six dry-
contact relay outputs at a remote location from a compatible terminal or communication module.
Digital control information is communicated between the ARM100 and the terminal via an RS-485
communication link.
An external 10 – 32 VDC power supply is required to operate the ARM100 module. The ARM100 is
only approved for installation in areas classified at SAFE.

ACM200 Safe Area Communication Module

The ACM200 converter can be used to convert the intrinsically safe current loop information from
COM4 or COM5 of the IND560x terminal to an RS-232 signal inside the safe area. The ACM200
converter can be used to obtain demand or continuous RS-232 data from the IND560x or can
convert RS-232 signals in the safe area to intrinsically safe ASCII data and send to the IND560x.
For a CL20mA or RS-422 or RS-485 signal inside the safe area, the ACM200 configured with the
CL/RS-422/RS-485 option can be used.If the ACM500 is already connected to the IND560x
terminal, it is not possible to connect the ACM200 converter. This is because both devices require
dedicated use of the COM4 and COM5 ports of the IND560x terminal. The ACM200 is designed to
communicate to the IND560x terminal using a copper wire communication cable at distances up to
300 m (1000 ft).
