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" | ||

||
config MB_FUNC_READWRITE_HOLDING_ENABLED | ||
bool "Read/Write Multiple Registers function" | ||

---help--- | ||
If the Read/Write Multiple Registers function should be enabled. |
