Shinko BCR2 Communication Instruction Manual

BCD2, BCR2, BCS2 (C5W, C5) No. BCx2CE5 2018.02 This manual contains instructions for communication functions of the BCD2, BCR2, BCS2. Serial communication and Console communication cannot be used together. When performing Serial communication, remove the tool cable (CMD-001) from the USB port of the PC and console connector ...

(Fig. 2.1-1) 2.2 When Using Communication Converter IF-400 (sold separately) (Fig. 2.2-1) Shield wire Connect only one end of the shield to the FG terminal to avoid a ground loop. If both ends of the shield wire are connected to the FG terminal, the circuit will be closed, resulti ...

Communication converter IF-400 (sold separately) has a built-in terminator. The terminator is mounted at the end of the wire when connecting multiple peripheral devices to a personal computer. The terminator prevents signal reflection and disturbance. Do not connect a terminator to the communication line because each BCD2, BC ...

Set communication parameters in Engineering mode 1. To enter Engineering mode 1, press and hold the and keys (in that order) together for approx. 3 seconds in RUN mode. Use the or key for settings (or making a selection). To register the set data, use the key. Set each communication parameter following the procedure belo ...

Stop bit • Selects the stop bit. • Selection item: 1 bit 2 bits Response delay time • Response from the controller can be delayed after receiving command from the host computer. • Setting range: 0 to 1000 ms SVTC bias • By connecting to Shinko programmable controllers [PC-900 or PC ...

Communication starts with command transmission from the host computer (hereafter Master) and ends with the response of the BCx2 (hereafter Slave). • Response with data When the master sends the Read command, the slave responds with the corresponding set value or current status. • Acknowledgement When the master sends the Writ ...

5.1 Transmission Mode Shinko protocol is composed of ASCII. Hexadecimal (0 to 9, A to F), which is divided into high order (4-bit) and low order (4-bit) out of 8-bit binary data in command is transmitted as ASCII characters. Data format Start bit: 1 bit Data bit: 7 bits (8 bits) Selectable Parity: Even (No parity, Odd) Selectable Stop bi ...

Checksum is used to detect receiving errors in the command or data. Set the program for the master side as well to calculate the checksum of the response data from the slaves so that communication errors can be checked. The ASCII code (hexadecimal) corresponding to the characters which range from the address to that before the chec ...
