ioPAC 8020 Rugged Remote I/O
Click&Go Introduction
5-2
Overview
Anyone can be a programmer! Moxa’s Click&Go local control
logic for the ioPAC 8020 eliminates the cumbersome
programming generally required for data acquisition, alarm
messaging, and local control tasks. No knowledge of the C
programming language or PLC ladders is required for field
applications. Instead, users familiar with IF-THEN-ELSE
statements will have no problem understanding the Click&Go interface and will be able to control I/O channels
and alarm messaging after a few simple steps. The configuration utility also makes the control process easy to
define and configure. Simply download the control logic to the ioPAC 8020 and Click&Go will be ready-to-go in
no time.
Click&Go performs various functions including local I/O control, remote output control, alarm generation and
messaging, and event-driven or time-based I/O status reporting. Click&Go eliminates the need for host
computers to continually poll I/O devices for status. Instead, the server itself is able to monitor the status of
each I/O device and take the appropriate action when the I/O status satisfies a user-defined condition. For
example, users may need to configure the Moxa ioPAC 8020 s to send a TCP/UDP message only when the
switch attached to DI-0 is turned on. This event-based structure results in a much improved response time and
a much reduced load on the host computer’s CPU and on network bandwidth. Simple IF–THEN–ELSE
statements are used to specify conditions that are required for certain actions to take place. Up to three
conditions, three actions, and three opposite actions (ELSE) can be combined in a rule, and you can define up
to 24 rules. Supported actions include sending SNMP traps or TCP/UDP messages to up to 10 hosts at a time.
Click&Go can also be used to map an input channel on one Moxa ioPAC 8020 to an output channel on another
ioPAC 8020 for peer-to-peer I/O communication. Up to five different IP addresses can be entered as the output
destination. Peer-to-peer I/O provides a very flexible and easy way to extend I/O signals or connect remote
on/off switches. It can be used, for example, to replace or extend the wiring of PLC or DCS systems over
Ethernet.
Click&Go Logic was developed to provide an easy and intuitive way to configure when and how I/O information
is transmitted over the network. Using simple IF-Then-Else statements, you set the conditions that need to be
satisfied and the resulting actions. Up to three conditions and three actions can be combined in any one rule,
and up to 80 rules can be defined in a ruleset. Each SNMP trap, TCP/UDP message can be transmitted to up to
10 hosts simultaneously.
