Upgrade information

Release Date

Ver. 3.21

Function addition, Improvement
(1) The maximum size of setting data for the event monitor function has been expanded from 64 kbyte to 128 kbyte. 64 kbyte or larger data creation and writing/reading to/from the PLC
require PCwin2 version 3.9 R01 or higher.
(2) The setting range of port No. when using the Ethernet general-purpose communication
method has been expanded from 1 to 65534.
(3) Hierarchical communication response time of FL-net has been improved.
(4) Improved the write life of FR registers and added a life-time notification function.
Bug fixes
(1) The phenomenon in which node duplication errors cannot be detected by the built-in L2
FL-net has been addressed.
(2) A special module error occurred when a program was written to the built-in Ethernet with
PCwin2 and read out simultaneously with another DM and PCwin2.
(3) A communication error at startup that occurs when the module configuration of BALLUFF IO-Link is set within the range of CH1 to CH7 in the built-in L1 EtherCAT has been addressed.
(4) Fixed a problem that application instruction error 1 occurs when FR register application instruction (FRCL) and write during program RUN are executed at the same time.
(5) Countermeasure for the phenomenon that Errors 10, 4E, and 36 occur in the CPU when output short-circuit diagnosis is enabled with three or more output cards.
(6) Fixed a phenomenon in which the number of received data was not set correctly when the SIO function of the built-in link was used with RS-422.
(7) Fixed a phenomenon in which reception is not possible when channel reset is performed during RS-422 transmission using the SIO function of the built-in link.
