Address

For all memory types except %L, enter the memory type and offset in the Address field. The address format is:

<memory type><address>

For example, to specify Register 1, the address is %R1. All offsets have a minimum value of 1.

The address of %L memory types requires the block name. Block names must be unique over all programs in the programmable controller.

Block names cannot begin with a numeric character.

The address format is:

%L<address><block name>

For example, to specify the fifth word in the %L domain in the program block ABC, the address is %L5ABC.

Note: The block name must be capitalized. For example, %L5ABC is correct, but %LAbc is not correct.

In addition to the standard diagnostic points, you can configure a set of Series 90 TCP/IP Triplex diagnostic points. The data structure type of all diagnostic points is analog UINT.

Update Criteria

The update criteria determine how the data will be requested.

Select On Change or On Scan for points whose values should be polled by Series 90 TCP/IP communications at regular intervals.

Select On Demand On Change or On Demand On Scan for points whose values should be polled by Series 90 TCP/IP communications at regular intervals when users are viewing them.

Select Unsolicited for points that are updated by devices.

Note: By default unsolicited data is disabled; it needs to be enabled for unsolicited data to be processed by this device communication interface.

Point Type

Select one of the following:

For device points, select Normal.

For diagnostic points, select Diagnostic. The Redundant TCP/IP Communications enabler uses the standard diagnostic points as well as the diagnostic points described below.

Address Offset

Enter the bit offset that corresponds to the bit position within the word.
