#This .INI file is also the HELP, MANUAL and HOW-TO file for mb2hal.

#Load the Modbus HAL userspace module as the examples below,
#change to match your own HAL_MODULE_NAME and INI file name
#Using HAL_MODULE_NAME=mb2hal or nothing (default): loadusr -W mb2hal config=config_file.ini
#Using HAL_MODULE_NAME=mymodule: loadusr -Wn mymodule mb2hal config=config_file.ini

#OPTIONAL: Debug level of init and INI file parsing.
# 0 = silent.
# 1 = error messages (default).
# 2 = OK confirmation messages.

#OPTIONAL: Set to 1.1 to enable the new functions:
# - fnct_01_read_coils

#NOTE: when using names be careful that you dont end up with two transactions
#using the same name.
