config MODBUS
bool "Modbus support via FreeModBus"
default n
config MB_ASCII_ENABLED
bool "Modbus ASCII support"
depends on MODBUS
default y
config MB_RTU_ENABLED
bool "Modbus RTU support"
depends on MODBUS
default y
config MB_TCP_ENABLED
bool "Modbus TCP support"
depends on MODBUS
default y
config MB_ASCII_TIMEOUT_SEC
int "Character timeout"
depends on MB_ASCII_ENABLED
default 1
---help---
Character timeout value for Modbus ASCII
The character timeout value is not fixed for Modbus ASCII and is therefore
a configuration option. It should be set to the maximum expected delay
time of the network.
config MB_ASCII_TIMEOUT_WAIT_BEFORE_SEND_MS
int "Timeout to wait before sending"
depends on MB_ASCII_ENABLED
default 0
---help---
Timeout to wait in ASCII prior to enabling transmitter
If defined the function calls vMBPortSerialDelay with the argument
MB_ASCII_TIMEOUT_WAIT_BEFORE_SEND_MS to allow for a delay before
the serial transmitter is enabled. This is required because some
targets are so fast that there is no time between receiving and
transmitting the frame. If the master is to slow with enabling its
receiver then he will not receive the response correctly.
config MB_FUNC_HANDLERS_MAX
int "Maximum number of Modbus functions"
depends on MODBUS
default 16
---help---
Maximum number of Modbus functions codes the protocol stack should support.
The maximum number of supported Modbus functions must be greater than
the sum of all enabled functions in this file and custom function
handlers. If set to small adding more functions will fail.
config MB_FUNC_OTHER_REP_SLAVEID_BUF
int "Size of Slave ID report buffer"
depends on MB_FUNC_OTHER_REP_SLAVEID_ENABLED
default 32
---help---
Number of bytes which should be allocated for the Report Slave ID command.
This number limits the maximum size of the additional segment in the
report slave id function. See eMBSetSlaveID() for more information on
how to set this value. It is only used if MB_FUNC_OTHER_REP_SLAVEID_ENABLED
is set to 1.
config MB_FUNC_OTHER_REP_SLAVEID_ENABLED
bool "Report Slave ID function"
depends on MODBUS
default y
---help---
If the Report Slave ID function should be enabled.
config MB_FUNC_READ_INPUT_ENABLED
bool "Read Input Registers function"
depends on MODBUS
default y
---help---
If the Read Input Registers function should be enabled.
config MB_FUNC_READ_HOLDING_ENABLED
bool "Read Holding Registers function"
depends on MODBUS
default y
---help---
If the Read Holding Registers function should be enabled.
config MB_FUNC_WRITE_HOLDING_ENABLED
bool "Write Single Register function"
depends on MODBUS
default y
---help---
If the Write Single Register function should be enabled.
config MB_FUNC_WRITE_MULTIPLE_HOLDING_ENABLED
bool "Write Multiple registers function"
depends on MODBUS
default y
---help---
If the Write Multiple registers function should be enabled.
config MB_FUNC_READ_COILS_ENABLED
bool "Read Coils function"
depends on MODBUS
default y
---help---
If the Read Coils function should be enabled.
config MB_FUNC_WRITE_COIL_ENABLED
bool "Write Coils function"
depends on MODBUS
default y
---help---
If the Write Coils function should be enabled.
config MB_FUNC_WRITE_MULTIPLE_COILS_ENABLED
bool "Write Multiple Coils function"
depends on MODBUS
default y
---help---
If the Write Multiple Coils function should be enabled.
config MB_FUNC_READ_DISCRETE_INPUTS_ENABLED
bool "Read Discrete Inputs function"
depends on MODBUS
default y
---help---
If the Read Discrete Inputs function should be enabled.
config MB_FUNC_READWRITE_HOLDING_ENABLED
bool "Read/Write Multiple Registers function"
depends on MODBUS
default y
---help---
If the Read/Write Multiple Registers function should be enabled.
