#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): #Using HAL_MODULE_NAME=mymodule: loadusr -Wn mymodule mb2hal config=config_file.ini #Common section [MB2HAL_INIT] #OPTIONAL: Debug level of init and INI file parsing. # 0 = silent. # 1 = error messages (default). # 2 = OK confirmation messages. # 3 = debugging messages. INIT_DEBUG=3 #OPTIONAL: HAL module (component) name. Defaults to "mb2hal". HAL_MODULE_NAME=mb2hal #OPTIONAL: Insert a delay of "FLOAT seconds" between transactions in order #to not to have a lot of logging and facilitate the debugging. #Useful when using DEBUG=3 (NOT INIT_DEBUG=3) #It affects ALL transactions. #Use "0.0" for normal activity. SLOWDOWN=0.0 #REQUIRED: The number of total Modbus transactions. There is no maximum. TOTAL_TRANSACTIONS=2 #One transaction section is required per transaction, starting at 00 and counting up sequentially. #If there is a new link (not transaction), you must provide the REQUIRED parameters 1st time. #Warning: Any OPTIONAL parameter not specified are copied from the previous transaction. [TRANSACTION_00] LINK_TYPE=tcp TCP_IP=192.168.16.55 TCP_PORT=502 MB_SLAVE_ID=1 FIRST_ELEMENT=5391 NELEMENTS=8 #REQUIRED: Modbus transaction function code (see www.modbus.org specifications). # fnct_02_read_discrete_inputs (02 = 0x02) # fnct_03_read_holding_registers (03 = 0x03) # fnct_04_read_input_registers (04 = 0x04) # fnct_15_write_multiple_coils (15 = 0x0F) # fnct_16_write_multiple_registers (16 = 0x10) #fnct_02_read_discrete_inputs: creates boolean output HAL pins. #fnct_03_read_holding_registers: creates a floating point output HAL pins. # also creates a u32 output HAL pins. #fnct_04_read_input_registers: creates a floating point output HAL pins. # also creates a u32 output HAL pins. #fnct_15_write_multiple_coils: creates boolean input HAL pins. #fnct_16_write_multiple_registers: creates a floating point input HAL pins. MB_TX_CODE=fnct_03_read_holding_registers #OPTIONAL: Response timeout for this transaction. In INTEGER ms. Defaults to 500 ms. #This is how much to wait for 1st byte before raise an error. MB_RESPONSE_TIMEOUT_MS=500 #OPTIONAL: Byte timeout for this transaction. In INTEGER ms. Defaults to 500 ms. #This is how much to wait from byte to byte before raise an error. MB_BYTE_TIMEOUT_MS=500 #OPTIONAL: Instead of giving the transaction number, use a name. #Example: mb2hal.00.01 could become mb2hal.plcin.01 #The name must not exceed 32 characters. #NOTE: when using names be careful that you dont end up with two transactions #usign the same name. HAL_TX_NAME=STBIn #OPTIONAL: Maximum update rate in HZ. Defaults to 0.0 (0.0 = as soon as available = infinit). #NOTE: This is a maximum rate and the actual rate may be lower. #If you want to calculate it in ms use (1000 / required_ms). #Example: 100 ms = MAX_UPDATE_RATE=10.0, because 1000.0 ms / 100.0 ms = 10.0 Hz MAX_UPDATE_RATE=0.0 #OPTIONAL: Debug level for this transaction only. #See INIT_DEBUG parameter above.
