Moxa MPC-2150Z-T [58/65] Etc elapsed time counter query

MPC-2150 Hardware Display Control Interface Commands

B-4

ETC (Elapsed Time Counter Query)

This command is to query the elapsed time that the MPC-2150 has been operated. The MPC-2150 will reply to

this command with an ACK attention code. The largest byte will be transmitted first.

The maximum indicator for this function is 99999 hours (defined into 5 bytes, numbers 0 to 9 each), equivalent

to 11 years. If this number is reached, the ETC will stop counting, and the ETC command will always reply with

maximum number of hours (99999).

Example:

Send ETC to query elapsed time:

0x07 0xFF 0x45 0x54 0x43 0x00 0x1D

ACK 99999 hours

06 FF 45 54 43 05 19 39 39 39 39 39 E2
