6.1 Loader Communication Functions 6.1 Loader Communication Functions The equipment equipped with communication functions via the loader interface, which enables data exchange to such devices as PC. The communication system composed of the one to one communication between a master (such as, personal computer) and a slave (the equipment). Note ● The system constructed with the equipment as slaves do not respond to messages issued by the master with broadcast queries are where the station number is “0”.
6.2 Loader Communication Specifications 6.2 Loader Communication Specifications Loader interface Item Specifications Electrical specifications EIA RS232C Transmission method 3-wire system, half duplex serial Synchronous method Asynchronous Connection mode 1:1 Station number 128 Communication speed 19.
6.3 Loader Connection 6.3 Loader Connection Warning DO NOT TURN THE POWER ON UNTIL ALL OF THE WIRING IS COMPLETED. THERE IS A RISK OF ELECTRICAL SHOCK OR DAMAGE. Communication terminal Loader communication port Loader connecting cable PWR PUM-C BUS LOADER RX1 TX1 STATION $%& ( ' # TX2 RX2 Connection with a loader communication port • Use an optional loader connecting cable (RS-232C). Loader connecting cable (RS-232C) PUMZ*L01 Master RS-232C PC etc.
6.4 Setting Loader Communication Parameters 6.4 Setting Loader Communication Parameters In order to perform communication between the master and the equipment properly, the setting below is necessary. • All communication conditions settings for both of the master and the equipment should be the same. Setting items for loader interface (The equipment) Items Setting range Factory-set value The value is fixed regardless of the setting of St. No. configuration SW. Station No.
6.5 MODBUS Communication Protocol 6.5 MODBUS Communication Protocol The communication system with MODBUS protocol always performs communication by using the procedure that “the master sends a command message first, and the applicable slave sends a response message back”. Communication procedure is shown in the flow chart below. The master sends a command message to the slave. The slave checks if the station number in the received message is the same as its own number.
6.5 MODBUS Communication Protocol When the station number in the command massage received is the same as its own number. Master Slave Command message When the station No. is the same Response message When the station number in the command message received is not the same as its own number. Master Slave Command message When the station No.
6.5 MODBUS Communication Protocol Message composition Command messages are composed of four parts; a station number, a function code, a data part, and an error check code, and sent them in the order above. Field Name Number of Bytes Station No. 1 byte Function code 1 byte Data part 2 to 64 bytes Error check code (CRC-16) 2 bytes Station No. This is the number allocated to a slave. It is fixed to “128”. Function code This code specifies the function for the slave to perform.
6.5 MODBUS Communication Protocol Slave response • Normal slave response A slave creates and replies the response message to each command message. The slave response message uses the same format as the command message. Contents inside the data part vary according to function codes.
6.5 MODBUS Communication Protocol Function code With MODBUS protocol, the different coil number/register number is allocated depends on the function code, and each function code is only available for a certain coil number/register number. The diagram below is shown the correspondence between the function code and the coil number/register number. Function code Code Coil / Register No. Function Target No.
6.5 MODBUS Communication Protocol Error Check Code (CRC-16) Calculation CRC-16 is 2-byte (16-bit) error check code. The calculating range is the starting position of the message (station number) to the end of the data part. A slave calculates the CRC of the message received, and does not send the response message back, if the result is not the same as the CRC code received. The flow for CRC-16 calculation is as below.
6.5 MODBUS Communication Protocol Transmission control procedure Master communication method Master should start communication following the rules below. 1. Provide more than 48-bit time blank state before sending the command message. 2. The interval between the sent messages should be less than 24 bit times. 3. The master will be in the receiving standby mode within 24 bit time after sending the command message. 4.
6.5 MODBUS Communication Protocol The equipment response The equipment, after detected the frame (detection of the blank state more than 24 bit time), runs that frame as the command message. In the case the frame message is for the own station, the equipment send the response message back; it takes about 1 to 30 ms for this operation. (How long it takes is depends on the contents of the command message.
6.6 Command and Transmission Frame Details 6.6 Command and Transmission Frame Details Reading Data Reading Word Data (Function Code: 03H) The unit reads word data continuously for the specified number of words from the first number to start reading from. The slave forwards the read word data from the upper number of bytes to the lower number. Note ● When reading out word data continuously, specification beyond the range of the relative address will result in no response.
6.6 Command and Transmission Frame Details • Message composition Master Slave Command composition (Byte) Response message composition (Byte) Station No. Station No.
6.6 Command and Transmission Frame Details • Example of message transmission When reading out the set value of “Device Type of Setting Area” from a programless communication module, the message composition is as follows. • “Device type of the setting area” relative address: 000Ah Master Slave Command message (Byte) Station No. 80H Function code Response Message (Byte) 03H Station No.
6.6 Command and Transmission Frame Details Reading out read-only word data (Function code: 04H) The equipment reads out the word data specified by the number of words to read out continuously from the number to start reading out. A slave sends the read out data in order of the upper bytes, the lower bytes. Function code 04H Max. number of readable words in one message 125 Relative address 0000H to OFDCH Register No.
6.6 Command and Transmission Frame Details • Example of message transmission When reading out “PLC inter-cycle time monitor” from the programless communication module, the message composition is as follows. • “PLC inter-cycle time monitor” relative address: 03EEh Master Slave Command message (Byte) Station No. 80H Function code Response message (Byte) 04H Station No.
6.6 Command and Transmission Frame Details Writing Data Writing word Data (1 word, function code: 06H) This writes the specified data to the specified number for word data. The master sends the data to be written from the upper number of bytes to the lower number. Function code 06H Max. number of readable words in one message 1 • Message composition Master Slave Command message composition (Byte) Station No.
6.6 Command and Transmission Frame Details • Example of message transmission This example shows when setting “Setting Area Device Size” for the programless communication module to 500 (01F4h). • “Setting Area Device Size” relative address: 000Dh Master Slave Command message (Byte) Station No. 80H Function code Number to specify writing (Relative address) Write word data CRC data INP-TN5A0202-E Response message (Byte) 06H Station No.
6.6 Command and Transmission Frame Details Write series of words (Function code: 10H) Write how long it takes to write words and the series of word information beginning from the start writing number. The master sent the writing word data in order of the upper, the lower. Function code 10H Max. number of readable words in one message 123 • Message composition Master Slave Command message composition (Byte) Station No.
6.6 Command and Transmission Frame Details • Example of message transmission This example shows when setting 1000 (03E8h) to "Setting Area Start Address (Lower, Upper)" of the programless communication module. • Setting area start address (Lower) = 1000 (=03EBh) • Setting area start address (Upper) = 0 (=0000h) • “Setting area start address (Lower)” relative address: 000Ch Master Slave Command message composition (Byte) Station No.
