(c) User frame receive format designation (address: 2020H to 2023H/2120H to 2123H)
In data reception using a user frame, specify the reception method for each combination of receive user
frames. This setting is valid in a setting shown in Page 268, Section 11.2.4 (2) (b) when it is set using a
combination that specifies a user frame.
For combinations other than those with the first frame only, data reception is performed using Format-0 even if Format-1 is
specified through the above reception method setting.
(d) Exclusive format-1 received data count designation (address: 2024H to 2027H/2124H
to 2127H)
• For a combination specifying Format-1 in the user frame receive format designation, specify the arbitrary
data word/byte count (size for performing a reception data read request to the programmable controller
CPU) when the applicable first frame is received. Specify this for each combination specifying Format-1.
• Specify a size within the size of the storage area for the reception data in the buffer memory.
• The unit for the setting value depends on the setting value given in the word/byte units designation.
