11 Outline 1. Features The PROFIBUS system is a system used to connect the robot controller or scattered input/output modules, etc., with dedicated cables, and to control these modules from the master module. The PROFIBUS system allows wiring to be reduced. 1 Master module Controls the entire PROFIBUS system. The PLC master module corresponds to this. n NOTE On the RCX240, the dedicated input of STD. DIO connector provided on the controller will be disabled except for an interlock signal (DI 11). When the Board condition (external 24V monitor control) of system parameters is set invalid, the interlock signal (DI 11) will also be disabled. On the RCX22x, the dedicated input of STD. DIO connector will be disabled, but the interlock signal (DI 11) in SAFETY connector enabled. Slave module Controlled by the master module in the PROFIBUS system. The robot controller corresponds to this. Slave module Controlled by the master module in the PROFIBUS system. [Wiring saving] One dedicated cable (5-wire) is used to connect the robot controller and PLC. This allows the entire system wiring to be reduced. c CAUTION An emergency stop terminal for hardwire is provided in the SAFETY connector on the robot controller. In the case of the RCX240, when the PROFIBUS system is used while STD. DIO is not used (external DC 24V power supply is not used), the Board condition (external 24V monitor control) of system parameters must be set invalid. If it is left valid, the STD. DIO interlock signal is enabled causing an error in the robot operation commands. [Emulated serialization on parallel DIO] By making the robot controller s internal settings without using a robot program, the various I/O devices, such as the sensors and relays mounted on the robot controller s parallel I/O can be controlled from the PLC as if they were PROFIBUS system I/O devices. 1-1

12 2. Mechanism 1 The mechanism of communication is explained in this section to provide an understanding of how the robot controller and master module operate via the PROFIBUS system. Outline Master module q ON/OFF information w Robot controller q The robot controller s ON/OFF information is sent to the master module via the network (PROFIBUS system cable). w The master module s ON/OFF information is set to the robot controller via the network (PROFIBUS system cable). * The robot controller monitors the ON/OFF information at a 10ms cycle. * The ON/OFF information consists of two words each of dedicated I/O words, 14 words each of general-purpose I/O words as word information, and 16 points each of dedicated I/O points, 96 points each of general-purpose I/O points as bit information. If the following is executed with the robot program in the robot controller, the bit information will be sent to the master module via the PROFIBUS system by q. SO (20)=1 Conversely, if the following is executed with the robot program, the bit information received from the master module via the PROFIBUS system will be monitored by w, and the robot controller will wait for the ON information. WAIT SI (20)=1 If the following is executed with the robot program in the robot controller, the word information will be sent to the master module via the PROFIBUS system by q. SOW (2)= 256 Conversely, if the following is executed with the robot program, the word information received from the master module via the PROFIBUS system will be substituted in integer variable A% by w. A% = SIW (3) 1-2

30 MEMO

31 Communication 1. State when robot controller power is turned ON The PROFIBUS system specification robot controller always starts operation in servo OFF state when the power turned ON. q When connection to PROFIBUS system is correctly established. The following conditions must be satisfied to correctly connect to the PROFIBUS system: The PROFIBUS system cable must be physically connected The station address must be correctly set The master module is operating normally When the robot controller is correctly connected to the PROFIBUS system, the normal state will be indicated with the LEDs on the PROFIBUS compatible module. At this time, the emergency stop signal and interlock signal in the PROFIBUS system will be validated, so both signals must be turned ON in the connection process. The emergency stop terminal in SAFETY connector is always kept valid. On the RCX22x, the interlock signal in SAFETY connector is also valid. On the RCX240, the interlock signal in STD. DIO connector is left valid unless the Board condition (external 24V monitor control) of system parameters is set invalid. When SAFE mode is enabled, service mode input signal is made valid with SI (02) in the PROFIBUS system. On the RCX22x, service mode input signal is also made valid with DI(02) in SAFETY connector. On the RCX240, when SAFE mode is enabled, service mode input signal is also made valid with DI(02) in SAFETY connector unless the Board condition (external 24V monitor control) of system parameters is set invalid. 3 w When connection to PROFIBUS system is incorrectly established The following causes can be considered a correct connection with the PROFIBUS system cannot be established: The PROFIBUS system cable is not physically connected The station address is set incorrectly The master module is not operating correctly When incorrectly connected to the PROFIBUS system, an abnormal state will be indicated on the PROFIBUS compatible module s LED. This also occurs when the master module is not operating correctly. The emergency stop signal and interlock signal in the PROFIBUS system are invalid in this case, so the robot controller can be operated independently. However, if the correct state has been established even once after the robot controller power was turned ON, the robot controller s emergency stop state cannot be canceled without correctly connecting to the PROFIBUS system. The emergency stop terminal in SAFETY connector is always kept valid. On the RCX22x, the interlock signal in SAFETY connector is also valid. On the RCX240, the interlock signal in STD. DIO connector is left valid unless the Board condition (external 24V monitor control) of system parameters is set invalid. When SAFE mode is enabled on the RCX22x, service mode input signal is also made valid with DI(02) in SAFETY connector. On the RCX240, when SAFE mode is enabled, service mode input signal is also made valid with DI(02) in SAFETY connector unless the Board condition (external 24V monitor control) of system parameters is set invalid. Service mode input signal in the PROFIBUS system cannot be invalidated when SAFE mode is enabled, so change the service mode setting system parameters. In this case, take full precautions to prevent improper settings that might lead to a hazardous situation. * For meanings of LED display, see Chapter 4 in this manual. 3-1

32 2. Communication with master module The method for communicating with the master module by using the robot program when the PROFIBUS system is correctly connected is explained in this section. 3 Communication c CAUTION Always refer to the PLC manual and check the settings for communication with the master module. SIW(0) and SIW(1) are viewed as dedicated input ports. The robot controller handles these ports as input ports of meaningful data, so do not use them as general-purpose input ports. Set these ports to "0" in most cases. n NOTE The SI statement in the robot language can be defined from SI0 ( ) to SI27 ( ), but the PROFIBUS compatible module accepts from SI0 ( ) to SI15 ( ). 2.1 Receiving data Data is received by reading the master module s output address data with the robot controller s input port. The correspondence of the master module s output addresses and robot controller input port numbers is shown below. Master module address Qn Qn+2 Qn+4 Qn+6 Qn+8 Qn+10 Qn+12 Qn+14 Qn+16 Qn+18 Qn+20 Qn+22 Qn+24 Qn+26 Qn+28 Qn+30 Robot controller input port No. SIW(0) SIW(1) SID(2) SIW(2) SIW(3) SID(4) SIW(4) SIW(5) SID(6) SIW(6) SIW(7) SID(8) SIW(8) SIW(9) SID(10) SIW(10) SIW(11) SID(12) SIW(12) SIW(13) SID(14) SIW(14) SIW(15) Q : Output address. n : Start address assigned by hardware configuration. Master module address Qn+32.0 to Qn+32.7 Qn+33.0 to Qn+33.7 Qn+34.0 to Qn+34.7 Qn+35.0 to Qn+35.7 Qn+36.0 to Qn+36.7 Qn+37.0 to Qn+37.7 Qn+38.0 to Qn+38.7 Qn+39.0 to Qn+39.7 Qn+40.0 to Qn+40.7 Qn+41.0 to Qn+41.7 Qn+42.0 to Qn+42.7 Qn+43.0 to Qn+43.7 Qn+44.0 to Qn+44.7 Qn+45.0 to Qn+45.7 Robot controller input port No. SI(00) to SI(07) SI(10) to SI(17) SI(20) to SI(27) SI(30) to SI(37) SI(40) to SI(47) SI(50) to SI(57) SI(60) to SI(67) SI(70) to SI(77) SI(100) to SI(107) SI(110) to SI(117) SI(120) to SI(127) SI(130) to SI(137) SI(140) to SI(147) SI(150) to SI(157) When reading the bit information from the master module output address with the robot controller, write the following command in the robot program in the same manner as the DI input port. WAIT command Assignment statement Example :To wait for Qn+34.0 to turn ON WAIT SI (20) = 1...* The robot program will wait for SI (20) to turn ON. Example :To read the Qn+34.0 to Qn+34.7 data into variable A A = SI2 ()... * The SI2 () data will be converted into a decimal and substituted into variable A. If SI2 () is 7Fh, variable A will be 127. When reading the word information from the master module s output address with the robot controller, write the following command in the robot program. Assignment statement n NOTE The word data read with SIW (n) has the uncoded little endian format. The double word data read with SID (n) has the coded little endian format. Example Example :To read the Qn+4 word data into variable B B = SIW (2)...* The SIW (2) data will be substituted into variable B as a decimal. If SIW (2) is 01FFh, variable B will be 511. :To read the Qn+4 and Qn+6 double word data into variable C C = SID (2)... * The SIW (2) and SIW (3) data will be substituted into variable C as a decimal. If SIW (2) is 0010h and SIW (3) is 0001h, variable C will be

33 Communication 2. Communication with master module c CAUTION Always refer to the PLC manual and check the settings for communication with the master module. SIW(0) and SIW(1) are viewed as dedicated input ports. n NOTE The SO statement in the robot language can be defined from SO2 ( ) to SO27 ( ), but the PROFIBUS compatible module accepts from SO2 ( ) to SO15 ( ). 2.2 Transmitting data Data is transmitted by writing the robot controller s output port data into the master module s input address. The correspondence of the master module s input addresses and robot controller output port numbers is shown below. Master module address Im Im+2 Im+4 Im+6 Im+8 Im+10 Im+12 Im+14 Im+16 Im+18 Im+20 Im+22 Im+24 Im+26 Im+28 Im+30 Robot controller output port No. SOW(0) SOW(1) SOD(2) SOW(2) SOW(3) SOD(4) SOW(4) SOW(5) SOD(6) SOW(6) SOW(7) SOD(8) SOW(8) SOW(9) SOD(10) SOW(10) SOW(11) SOD(12) SOW(12) SOW(13) SOD(14) SOW(14) SOW(15) I : Input address. m : Start address assigned by hardware configuration.

SET/RESET command Assignment statement Example :To turn Im+34.0 ON SET SO (20) or SO (20) = 1.* SO (20) will turn ON. Example :To write variable A data into Im+34.0 to Im+34.7 SO2 () = A...* The variable A data will be converted into a binary and substituted in SO 2(). If variable A is 127, SO2 () will be 7Fh. When writing the robot controller word information into the master module s input address, write the following command in the robot program. Assignment statement 3 n NOTE The word data written with SOW (n) has the uncoded little endian format. The double word data written with SOD (n) has the coded little endian format. Example Example :To write 512 into Im+4 as word data SOW (2) = * 512 is substituted in SOW (2), and SOW (2) becomes 0200h. :To write as the double word data for Im+4 and Im+6 SOD (2) = * is substituted in SOD (2), SOW (2) becomes 1111h and SOW (3) becomes 0001h. 3-3

34 3. Direct connection by emulated serialization on parallel DIO The robot controller's parallel input data can be transferred to the serial output data regardless of the robot program. Likewise, the robot controller's serial input data can be transferred to the parallel output data. Using this function, I/O devices such as a sensor or relay connected in parallel to the robot controller can be used like a device connected via PROFIBUS to the master module.
