6.1.3 Modbus I/O
The Modbus I/O protocol can be selected to communicate on the available serial ports. The Modbus I/
O is actually a Modbus/RTU master implementation that is dedicated to communicating with serial
Modbus/RTU slaves such as RTD input modules. Up to three (3) Modbus/RTU slaves can be
connected to the same bus polled by the Modbus I/O implementation. These are named I/O Module A,
I/O Module B and I/O Module C. Each of the modules can be configured using parameters in the
following two tables.
Table. 6.1.3 - 136. Module settings.
Name Range Description
I/O module X
address
0…247
Defines the Modbus unit address for the selected I/O Module (A, B, or C). If this setting
is set to "0", the selected module is not in use.
Module x
type
0: ADAM-4018+
1: ADAM-4015
Selects the module type.
Channels in
use
Channel
0…Channel 7 (or
None)
Selects the number of channels to be used by the module.

IEC61850. AQ-21x frame units support Edition 1 of IEC 61850.
AQ-25x frame units support both Edition 1 and 2 of IEC61850. The following services are supported by
IEC 61850 in Arcteq devices:
• Up to six data sets (predefined data sets can be edited with the IEC 61850 tool in AQtivate)
• Report Control Blocks (both buffered and unbuffered reporting)
• Control ('Direct operate with normal security’, ’Select before operate with normal
security, ’Direct with enhanced security’ and ’Select before operate with enhanced
sequrity’ control sequences)
• Disturbance recording file transfer
• GOOSE
