Added H1ECATC1_PLC2.ini, H1ECATY1_PLC1.ini, H1ECATY1_PLC2.ini, H1ECATY1_PLC3.ini to master file, removed H1EDCU_ECATC1.ini. Also edited H1EDCU_DUST.ini to include H1 diode room dust monitor channels. Restarted data concentrator, but data concentrator could not parse the H1ECATC1_PLC2.ini file. Error message "failed to locate first section in ...H1ECATC1_PLC2.ini" Edited the new H1ECAT* files, found "units=" missing actual units. Corrected, but the data concentrator still failed with the same error. Changed slope from 1 to 1.0, removed ^M from the end of the lines, no change, data concentrator still failed. Finally commented out the H1ECAT*.ini files to restart the data concentrator, as 20 minutes had passed. Examined the H1ECATC1_PLC2.ini file with "od -c", found 2 unprintable characters at the beginning of the file (octal 377, 376) at the beginning of the file, and each "normal" character has a trailing 000 (byte of value 0) after... 0000000 377 376 [ 000 d 000 e 000 f 000 a 000 u 000 l 000 Compare with a working .ini file: 0000000 [ d e f a u l t ] The script that generated the H1ECAT*.ini files needs some repair.
