SYNOPSIS
- Default component name
-
loadusr -W mb2hal config=config_file.ini
- Custom component name
-
loadusr -Wn mymodule mb2hal config=config_file.ini
DESCRIPTION
MB2HAL is a generic non-realtime HAL component to communicate with one or more Modbus devices. It supports Modbus RTU and Modbus TCP.
See https://linuxcnc.org/docs/html/drivers/mb2hal.html for more information.
PINS
fnct_01_read_coils:
mb2hal.m.n.bit bit out
mb2hal.m.n.bit-inv bit out
fnct_02_read_discrete_inputs:
mb2hal.m.n.bit bit out
mb2hal.m.n.bit-inv bit out
fnct_03_read_holding_registers:
mb2hal.m.n.float float out
mb2hal.m.n.int s32 out
fnct_04_read_input_registers:
mb2hal.m.n.float float out
mb2hal.m.n.int s32 out
fnct_05_write_single_coil:
- mb2hal.m.n.bit bit in
-
NELEMENTS needs to be 1 or PIN_NAMES must contain just one name.
fnct_06_write_single_register:
mb2hal.m.n.float float in
- mb2hal.m.n.int s32 in
-
NELEMENTS needs to be 1 or PIN_NAMES must contain just one name.
Both pin values are added and limited to 65535 (UINT16_MAX). Use one and let the other open (read as 0).
fnct_15_write_multiple_coils:
mb2hal.m.n.bit bit in
fnct_16_write_multiple_registers:
mb2hal.m.n.float float in
- mb2hal.m.n.int s32 in
-
Both pin values are added and limited to 65535 (UINT16_MAX). Use one and let the other open (read as 0).
Each transaction
- mb2hal.m.num_errors u32 in
-
Error counter
m = HAL_TX_NAME or transaction number if not set
n = element number (NELEMENTS)
Example:
mb2hal.00.01.int (TRANSACTION_00, second register)
mb2hal.readStatus.01.bit (HAL_TX_NAME=readStatus, first bit)AUTHOR
