This version still support old ESI files which contains revision 2, but it is recommended to update to newer ESI file to support new object directory structure.

General

• fix noisy overvoltage detection which prevents powerfail
• fall back to bootloader if boot after firmware update fails
• reduce undervoltage detection by 0.5V
• adapt brightness of AP LEDs for CPX-AP-A-EC-M12

AP-System

• change 4IOL to default variant if OE-variant is detected
• add more details on transmission error counter
• fix parameter read of input data can cause device lost during operation
• enable wirefracture maintenance diagnosis
• enable diagnosis during startup issues
• fix get device status for output only systems
• fix upstart with MPA/VTSA gateways under slow starting voltage ramps
• improve transmission quality

EtherCAT

• do not raise diagnosis if fixed PDO is used and not slot configuration is written
• fix diagnosis (watchdog and toggle bit) during OP2SAFEOP transition or communication lost on EtherCAT
• fix Complete Access for index 0xA0xx for IO-Link devices (wrong subitem count)
• !! change CoE indexes to a index distance of 16 for 0x2nn0,0x6nn0,0x7nn0,0x9nn0,0xAnn0
• update FSoE parameter
• fix AoE response on read read error and all write access to IOL commands
• increment revision to 3 due to the breaking change with the index distance (preparation for FSoE support)
• fix output only AP systems throw toggle bit error diagnosis in DC mode
• add support for string parameter in CoE module parameter (0x2nn0)

Webserver

• allow write of string parameter
• fix broken websites (http status 500 - with haserl error)

General

• fix update with FFWP files which contains history longer than 1024 bytes
• set Maintenance LED if maintenance diagnosis is active

AP-System

• add parameter checks for read-only parameter and wrong values on write
• fix update of CPX gateways
• add retries to parameter access in case of temporary service errors
• add non-volatile diagnosis trace
• diagnosis trace include diagnosis parameter
• add system start diagnosis to AP diagnosis trace
• filter wirefracture diagnosis
• reduce external timeout if AP system fails for parameter or file service
• allow reset in large systems of all devices after firmware update
• device lost diagnosis fixed under certain conditions

Webserver

• decorate process data with strike-through on invalid data
• show CBUS diagnosis
• TwinCAT Startup Export only export startup parameter
• show PL status for devices
• do not display invalid process data in configuration state
• fix loading diagnosis trace on slow connection

EtherCAT

• add FoE support for Datastorage (filename iol_ds_x_y)
• fix ISDU access via CoE to 4IOL module at address 1
• add AoE ISDU read/write support as defined in ETG5001.6220
• add IO-Link eventcodes per port in CoE Module Diagnosis (0xA0xx)
• Sync DC timestamp to system time
