MbusRtuSlaveProtocolsetFrameTolerance Method |
Configures the tolerance the RTU protocol engine
* should apply for the detection of inter-frame gaps.
*
Namespace: FieldTalk.Modbus.Slave
Assembly: FieldTalk.Modbus.Slave (in FieldTalk.Modbus.Slave.dll) Version: 2.11.0-eval+eb1ecbe71c969eff5d7c05d58da16dade0474678
SyntaxParameters
- frameToleranceMs
- Type: SystemInt32

Return Value
Type: Int32BusProtocolErrors.FTALK_SUCCESS on success or error code. * See BusProtocolErrors for possible error codes.
Remarks
* Modbus RTU uses inter-frame gaps (silence periods) to mark
* start and end of Modbus packets.

| For strict Modbus compliance this should be set to 0. * |
* There are cases were longer silence periods may appear in the * data stream due to the hardware used (USB dongles) or * the device driver or the scheduling of the operating system. * This value can then be increased to compensate. * In a point-to-point communication system (eg RS-232) this * value can be safley increased. However in a multi-point system * were other slave devices are on the line, this value should be * set to the lowest possible value in order to maintain * interoperability with other Modbus equipment. *

| This mode must be set before starting * the server in order to come into effect. |
