DS-CL28_42-SA Communication Function Technical Manual

Communication Protocols 1.1 Communication Functions DS-CL28/42-SA can control up to 16 axis by multidrop link at RS-485 Pay attention that when Windows goes into standby or power-save mode, serial communication might be disconnected. When the system is recovered from standby mode, it should be connected again with serial communication. This is also applicable to the library provided.

Communication Protocols 1.1.2 RS-485 Communication Protocol (Ver 6) There are 2 kinds of program version for DS-CL28/42-SA. This manual support for Version 6 level. (DS-CL28/42-SA support version 6 only.) After running the user program(GUI), You can check the version with ‘About Ezi-MOTION Plus-R GUI’ menu in ‘Help’ menu. ※ Version 6.45.5.41 and later versions of “Ezi-MOTION Plus-R GUI” supports DSCL28/42-SA

Communication Protocols (1) Overview of Communication Frame ① 0xAA : Delimited byte ② 0xAA 0xCC : Displays that the Frame locates in header. ③ 0xAA 0xEE : Displays that the Frame locates in tail. ④ If any of the Frame data is ‘0xAA’, ‘0xAA’ should be added right after it. (byte stuffing 1) ) ⑤ If any data following ‘0xAA’ is not ‘0xAA’, ‘0xCC’ or ‘0xEE’, it displays that an error has occurred. Detailed Frame Data is configured as follows: ① Slave ID : Dive module number (0~15) connected to the PC communication port. ② Frame type : To designate command type of relevant frames. For the...

Communication Protocols 1.1.3 CRC Calculation Example The following program source is included in a file (file name : CRC_Checksum.c) provided with the product.

Communication Protocols 1.1.4 Response Frame Format and Communication Error(ver 6) When any command is sent, the basic format of Frame at the response side is same. However, there is a difference in case of Frame Data, which ‘communication status’ is added as shown below. ① Slave ID : Same to sending Frame. (When this is not same to sending data, it should be recognized as the error status.) ② Frame type : Same to sending Frame. (When this is not same to sending data, it should be recognized as the error status.) ③ Data : When simple executive instructions are sent, this data cannot be...

Communication Protocols (1) If ‘Header’ and ‘Slave ID’ values in the sending Frame are abnormal, there is no response from the drive. (2) If the communication status is displayed to ‘130’, the size of response data is ‘0’ byt

Communication Protocols 1.2 Definition of Frame Type (Ver 6) 1.2.1 Frame Type of DS-CL28/42-SA

Communication Protocols Control Parameter *1) V06.01.30.22 and later versions(DS-CL28/42-SA) of firmware supports this functions.

Communication Protocols 1) This parameter is not used in V06.01.30.22 and later version (DS-CL28/42-SA). It can be set by using IO Settings.

Communication Protocols 1.2.4 Definition of Input Pin This displays the detailed description for 0x21 Frame type. This command is applicable to 32 signals in the control input port. The user can use signals for test as if they are inputted without actual input signal. The following table shows bit mask values by each signal. 1) V06.01.30.22 and later F/W version supports this signal. 1. Sending data to turn ON the Jog+ port Example 2. Sending data to turn ON the Jog+ port

Communication Protocols 1.2.5 Definition of Status Flag Refer to ‘motion_define.h’ of include files 1) Only V06.01.30.22 and later F/W version supports this flag. Page | 2

Communication Protocols 1.2.6 Position Tanle Item (V06.01.30.22 and later F/W version supports PT function) Refer to ‘motion_define.h’ of include files

Communication Protocols 1.2.7 Information of Motors Firstly the number and 2~3 characters are display the motor size and length 28L : Motor Flange size is 28mm and Long size Second field is the motor maker information. Programming There are 2 method of programming for driving DS-CL28/42-SA The first is normally used method that using Visual C++ language under window system of PC. Library that serviced together with DS-CL28/42-SA have to be used. Refer to 「2. Library for PC Program」 The second method can be accomplished by sending command characters directly to DSCL28/42-SA. The user have to...

2. Library for PC Program (Ver 6) 2.1 Library Configuration To use this library, C++ header file(*.h) and library file(*.lib or *.dll) are required. These files are included in “\\DINGS\\Ezi-MOTION Plus-RnE\\include\\” The following contents should be included in a source file for development. #include “\\DINGS\\Ezi-MOTION Plus-RnE\\include\\FAS_EziMotionPlusR.h” #include “\\DINGS\\Ezi-MOTION Plus-RnE\\include\\COMM_Define.h” #include “\\DINGS\\Ezi-MOTION Plus-RnE\\include\\MOTION_DEFINE.h” #include “\\DINGS\\Ezi-MOTION Plus-RnE\\include\\ReturnCodes_Define.h” Also, library files are as...

(1) The following table describes values returned when each library(DLL) function is used. The user can check the values returned at the library(DLL) function. In case of low-level programming, this service not provided. (2) The following table shows return values included commonly in all libraries. The user can check - 31 - Library for PC Program (Ver6) the result (communication status, running status) judged by the drive. When the user develops programs by using protocols without libraries (DLL), they are available as well.
