固件版本為3.10或更低的模塊
版本可能報告意外和高度間歇性的輸入/輸出丟失
VersaMax模擬輸入模塊的模塊故障
IC200ALG240、IC200ALG620和IC200ALG630；模擬輸出模塊，IC200ALG331；混合離散/高速計數器模塊，IC200MDD841；和串行通信模塊，IC200CMM020。對于大多數用戶來說，這些故障永遠不會發生。此問題已在IC200GBI001固件中更正版本3.20。
VersaMax模擬輸入模塊IC200ALG240、IC200ALG620和IC200ALG630安裝在具有NIU固件的Genius輸入/輸出站中
WOODWARD 8446-1019工控調速器版本3.20必須升級到固件版本1.20或更高版本。以前版本的模擬輸入模塊固件可能會產生與任何版本一起使用時，意外丟失I/O模塊故障的Genius NIU固件，包括版本3.20。一個完全模擬模塊固件中的不同問題導致這些故障。但是，輸入/輸出故障表條目中的故障是由這兩個問題引起的包含相同的故障位置和額外的數據信息。限制和未決問題
? 當新配置的存儲被中斷時（例如卸下串行電纜），Genius NIU通常會恢復
操作以匹配以前的配置。但是，如中斷發生在某個2秒窗口內，Genius
NIU不會恢復增強診斷操作。EDMLED將熄滅。重新嘗試存儲新配置，或關閉GNIU電源以恢復到以前的配置。
modules with firmware version 3.10 or earlier
versions may report unexpected and highly intermittent Loss of I/O
Module faults for the VersaMax analog input modules
IC200ALG240, IC200ALG620 and IC200ALG630; the analog
output module, IC200ALG331; the Mixed Discrete / High-Speed
Counter Module, IC200MDD841; and the Serial Communications
module, IC200CMM020. These faults never occur for most users.
This issue has been corrected in IC200GBI001 firmware
version 3.20.
VersaMax analog input modules IC200ALG240, IC200ALG620 and
IC200ALG630 installed in a Genius I/O station with NIU firmware
version 3.20 must be upgraded to firmware version 1.20 or later.
Previous versions of analog input module firmware may produce
unexpected Loss of I/O Module faults when used with any version
of Genius NIU firmware, including version 3.20. An entirely
different issue in the analog module firmware causes these faults.
However, I/O Fault table entries for the faults caused by both issues
contain identical Fault Location and Extra Data information.
Restrictions and Open Issues
?
When a store of a new configuration is interrupted (for example, by
removal of the serial cable), the Genius NIU generally reverts
operation to match the previous configuration. However, if the
interruption occurs during a certain 2-second window, the Genius
NIU does not restore Enhanced Diagnostics operation. The EDM
LED will be OFF. Re-try the store of the new configuration, or
power-cycle the GNIU to revert to the previous configuration.
