[Firmware v. 11] The EC-C1200 inverter supports configuring the current time and date over CAN bus by using the standard messages as defined by the CANopen or J1939 specifications.
Since the RTC of the inverter is reset when the 24 V auxiliary power is shut off, the time and date of faults which have occurred in the fault log are less useful in troubleshooting. However, using the time/date messages the inverter's clock can be kept always at the correct time, allowing for more efficient troubleshooting and diagnostics. The time/date cannot be adjusted directly with PowerUSER.
Refer to the latest communication manuals for more information about the time/date messages.
Setting the time/date in J1939:
The internal time of the EC-C1200-450 inverter can be set by using the standard TDA message. The message is sent with PGN 54528 (0xD500) + inverter address.
For example: if the inverter's CAN address is 253 (0xFD), the resulting message ID/header will be 0x00D5FD00 (priority 00, source address 00).
Note: Messages with values outside of the presented valid ranges will be ignored and the time will not be set.
Setting the time/date in CANopen:
The internal time of the EC-C1200-450 inverter can be set by using the TIME protocol. TIME protocol uses a 6-byte message with the COB-ID 100h. The first 4 bytes contain the time of day as milliseconds since midnight. The last 2 bytes contain the calendar date as the number of days since January 1st, 1984.
For example: on January 1st, 2020 at noon (12:00) the time is 12 hours = 720 minutes = 43 200 seconds = 43 200 000 milliseconds since midnight. 43 200 000 as a hexadecimal value equals 0x02932E00. Similarly, it is 13,149 (0x335D) days since January 1st, 1984. Therefore, the data that needs to be sent is 00 2E 93 02 5D 33. Attempts to set the time to before year 2000 or after year 2035 will be ignored.
Note: With firmware version 7, only the CANopen TIME protocol is supported. It is not possible to set the inverter clock in a J1939 variant device with firmware 7.
