Abstract

The present invention aims to reduce an operation burden related to the change of reception processing in a master device when a device connected to a slave device is changed. A device communication managing unit (10) transmits the data received by a device (20) communicating with a device communication port (110) in a first mode to a field network (50) by using a data format used for transmitting the data received by the device (20) communicating in a second mode.

Claims

1. A slave device, connected to a controller as a master device through a network, and having a communication port connected to a device, the slave device comprising:

a mode setting part, setting the device connected to the communication pot to communicate in a first mode or a second mode, the first mode being a mode of only receiving 1-bit data and the second mode being a mode of receiving more than 1 bit of data; and

a transmitting part, transmitting the data received from the device communicating in the first mode to the network in a data format when the mode setting part sets the first mode, wherein the data format is used for transmitting the data received from the device to the network when the mode setting part sets the second mode.

2. The slave device according to claim 1, wherein

the transmitting part stores the 1-bit data received from device to a predetermined position of the data format when the mode setting part sets the first mode, and stores a predetermined value in a position except for the predetermined position of the data format.

3. The slave device according to claim 1, characterized by further comprising:

a storage part, storing configuration information comprising recognition information of a device predetermined to be connected to the communication port; and

a comparing part, executing comparison processing when the mode setting mode sets the second mode, and executing no comparison processing when the mode setting mode sets the first mode, wherein the comparison processing is for determining a consistency of the recognition information of the device included in the data received from the device and larger than 1 bit and the recognition information included in the configuration information stored by the storage part.

4. The slave device according to claim 1, wherein

IO-Link®

is used to communicate with the device.

6. An information processing program, configured to use a computer as the slave device according to claim 1 to exert functions, and configured to use the computer as the mode setting part and the transmitting part to exert functions.

7. A computer-readable recording medium, recording the information processing program according to claim 6.

5. A control method, being a control method of the slave device which is connected to a controller as a master device through a network and having a communication port connected to a device, the control method comprising:

a mode setting step, setting the device connected to the communication pot to communicate in a first mode or a second mode, wherein the first mode is a mode of only receiving 1-bit data and the second mode is a mode of receiving more than 1 bit of data; and

a transmitting step, transmitting the data received from the device communicating in the first mode to the network in a data format when the first mode is set in the mode setting step, wherein the data format is used for transmitting the data received from the device to the network when the second mode is set in the mode setting step.
