11.6.4 Device number (serial number)
The device number is assigned individually for each device. The device number is the unique identification of the
RESISTRON
®
Temperature Controller RES-5009 in a CAN network. The device number is divided into two parts
to comply with the message format (  section 11.4 "ROPEX CAN protocol" on page 77). Each part contains three
digits stored in “Value.H” and “Value.L” in BCD format.
11.7 Reading and setting the internal clock
Since only a maximum of two byte values are transmitted per CAN message, the time information must be split
over several CAN messages. To ensure that the time information is exchanged consistently between the internal
clock and the CAN interface, the internal clock is not accessed directly, but via an intermediate buffer. With CAN
message 0x0004, 0x001F, the current system time is transferred to the intermediate buffer. The intermediate
buffer can then be read out with further CAN messages.
To set the internal clock, first all time information must be loaded into the intermediate buffer and then the content
of the intermediate buffer can be transferred to the internal clock with CAN message 0x0004, 0x0020. It then con-
tinues to run with the transferred time information.
The status of the internal clock can be requested via CAN message 0x0004, 0x001E. The response 0x001D con-
tains 4 bits:
Bit 0: Internal clock present (indicates that the internal clock is present)
Bit 1: Time inaccurate (the temperature compensation has been deactivated, because the voltage buffering has
reached a critical value)
Bit 2: Time invalid (there was a fallback to the last stored time, because the voltage buffering failed)
Bit 3: Setting clock (at the moment the transfer from the intermediate buffer to the internal clock is taking place).
