1.13. Safe Area Communication Options

1.13.1.

ACM500 Communication Module and Accessories

When Ethernet access, additional serial ports, or a PLC interface is required, an ACM500
communication module must be connected to the IND560x. The ACM500, which must be located
in a non-hazardous area, receives data from the IND560x through the fiber optic interface or the
intrinsically safe current loop interface. The ACM500 provides expansion slots for an
Ethernet/COM2/COM3 option board and a single PLC option. Refer to the ACM500 Technical
Manual or Installation Manual for details.
The following options for the IND560x require the use of the ACM500 communication module in the

Ethernet/COM2/COM3

The Ethernet port can be used for FTP transfer of tare and target tables and complete setup files. It
also provides a TCP/IP port to transmit demand templates, continuous data, for access to data via
the shared data server and to send email alerts when calibration expires or fails. This port can also
be used for backing up and restoring the terminal configuration, using the METTLER TOLEDO
InSite™ SL program.
COM2 provides RS-232 communication at rates from 300 to 115.2k baud. COM3 supports the
same baud rates and provides an RS-232, RS-422, or RS-485 connection. COM3 can be used to
update the firmware of the IND560x using the InSite™ CSL program.
When using COM2 or COM3 serial ports in the ACM500, it is recommended to use a network
transmission baud rate of at least 9,600 Baud. Using COM2 or COM3 serial ports with network
