• The problem that for e-mail sending, when the signature algorithm of SSL certificate for an e-mail server connected to the
DL8 is SHA-2, an e-mail sending error may occur is resolved.
*
During recent years, as signature algorithm of SSL certificate migrates from SHA-1 to SHA-2, sending e-mail is not avail-
able even with an e-mail server which sends e-mail correctly. For users who are using the firmware version earlier than
listed above, consult M-System.

• With earlier versions from shown above, when one sub-node out of sub-nodes (remote I/Os) connected to a gateway
(72EM2-M4 or IB10W2) with Modbus-RTU generates communication error, it is detected as node error of the gateway
and the communication with all sub-node is disconnected. With later versions shown above, it is detected as communica-
tion error of each sub-node. By this change, if a communication error from a sub-node is detected, communication with
other sub-nodes is maintained. (When a communication error with gateway is detected, as same as previous versions,
communication with all sub-node is disconnected.)

• Fixed the following problem. With Modbus/TCP master function of the version 1.8.x, when the setting is written to the
web-enabled remote terminal unit with DLCFG during detecting node error*, sometimes “Failed to save” is displayed and
it fails to write.

With system log, the period between recording “Modbus/TCP node error node=n” and recording return message of the
node “Modbus/TCP OK node=n”.
