Ethernet/Serial Ports

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 a demand template
or continuous data for remote configuration using the METTLER TOLEDO InSite
program, and for direct access to data via a shared data server.
COM2 provides RS-232 communication at rates from 300 to 115.2k baud. COM 3
supports the same baud rates and provides an RS-232, RS-422, or RS-485
connection.

PLC Interfaces

The IND560 PLC interface options include Analog Output, A-B RIO, and PROFIBUS
L2DP.

Analog Output

Analog Output refers to the representation of an internal system variable using a
proportional electrical signal. Analog Output can be used to transmit a measured
value, such as the gross or net weight. Another use for Analog Output is as a
control signal for some external device, such as a control valve, where the amount
of valve opening is proportional to the analog signal commanding its operation.
Such outputs are used to control the flow rate of material into or out of a vessel.
Both 0-10 volt DC and 4-20 mA signals are provided.
A-B RIO
The A-B RIO option enables data exchange by bi-directional communications using
the Discrete Data Transfer or Block Transfer mode. The IND560 Terminal initiates a
communication exchange with the PLC approximately 20 times per second
utilizing the Allen-Bradley Discrete Data Transfer protocol. This communication is a
high-speed, real-time message interface between the IND560 Terminal and the
PLC for process control. Division, integer, and floating point values are supported.
The IND560 A-B RIO interface also supports Block Transfer mode for transmission
of larger amounts of data. Additional details of this interface can be found in the
IND560 PLC Interface Manual on the documentation CD.
PROFIBUS L2DP
The IND560 Terminal communicates to a PROFIBUS-DP master according to
DIN 19 245. The PROFIBUS option consists of a module and software that resides
in the IND560 Terminal, which implements the data exchange.
1-10
The remote I/O is supported with the ARM100 remote module that provides
dry-contact outputs. The inputs are passive on the ARM100. An external
24-volt DC supply is required to operate the ARM100.
A total of 12 inputs and 18 outputs are supported through a maximum of three
options.
