2-7 Restrictions
2-7-1 The behavior of 2 word number in the NS-Designer test function
In the temperature controller, a value equivalent to 2 words (32 bits) is stored for each
communications address, but in the test function, the first 16 bits and the last 16 bits behave
as one and the same value. For that reason, test function will not operate successfully when
2 word numbers are designated.
2-7-2 Address display when address error occurs
When faulty device is set to communications address set in functional object, this
communications address is displayed in the device setting error dialogue.
If the communications address is allocated to the temperature controller, not the address for
the temperature controller set with the NS-Designer, but the address in the PLC address
format is displayed. Addresses will be converted as shown below.
