Integrated PLC protocols Function overview

2 Function overview

2.1Integrated PLC protocols

Mitsubishi Alarm Modems can communicate directly with the PLCs of leading manufacturers using the relevant PLC protocol, and access PLC variables, markers and ports via the PLC pro- gramming interface. This can be achieved without having to adapt the PLC program or load a special function block for communication.

These protocols are supported:

￿Mitsubishi Alpha XL

￿Mitsubishi MELSEC FX1S/FX1N and FX2N/FX2NC

￿Mitsubishi System Q (in preperation)

2.2Alarming with acknowledgment

Mitsubishi Alarm Modems are fully automatic and can send status and fault mes- sages to any recipient via SMS, fax, e-mail or Express E-Mail. Messages can be triggered by PLC variables.

Address book:	The SMS, fax and e-mail addresses (max. 100) are
	managed in an address book.
Messages:	The message texts (max. 100) can contain up to 100 actual
	values from the PLC and can be of any required length
	when used with faxes and e-mails.
Alarms:	Up to 100 alarms and actions such as switching commands
	can be defined.
Alarm cascade
and acknowledgments:	Any number of freely definable alarm levels can be set up if
	message acknowledgment is required. If a message is not
	acknowledged within a specified time, one or several
	recipients can be notified. This can be cascaded
	as required.

2.3Remote switching via SMS and Express-E-Mail

A short command via SMS or Express E-Mail can switch the optional outputs of the Mitsubishi Alarm Modem and those of a connected PLC. PLC variables can also be set in this way.

The execution of the command can also be acknowledged. 100 SMS switch commands with up to 10 parameters each can be defined as required. PLC variables can be queried simply and quickly by SMS command without the need for a PC.
