1. Functions Data Swap Function 4 4 Data Swap Function The high and low bytes are swapped in word units when input or output data are sent to or received from the master station Use this function when the used master station handles the high and low bytes of word data in reverse to those of the ME2PB1 L This function enables you to swap upper and lower bytes to exchange I O data without the need to create a special sequence program for the swapping Operation outline for swap function The data stored in the input sending area are sent to the master station after their high and low bytes have been swapped The data received from the master station are stored into the output receiving area after their high and low bytes have been swapped Master station ME2PB1 L Input data Input sending area Data 1 Data 1 Data 1 Data 1 Data1 Data L D Input image 4 2 Data 2 Data 2 Data 2 D Data 2 Data 2 D Q 1 D Output data S Output receiving area Data 3 Data 3 Data 3 Data 3 Data3 Data3 OQ i m O i H i Output 1 m 1 i 1 image 4 Data4 Data4 Data4 Data4 Data4 Data 4 L HW M d E l 4 eo Y Hi Profibus DP data communication byte LOW byte Fig 4 11 Data are swapped between the ME2PB1 L and the master statio

12. Safety guidelines Precautions to prevent damages by electrostatic discharge Electronic devices and modules can be damaged by electrostatic charge which is conducted from the human body to components ofthe controller Always take the following precautions when handling the controller CAUTION Before touching a module of the controller always touch grounded metal etc to discharge static electricity from human body Failure to do so may cause the module to fail or malfunction Wear isolating gloves when touching the powered controller e g at maintenance during visual check Youshouldn t wear clothing made of synthetic fiber at low humidity This clothing gets a very high rate of electrostatic charge Design Precautions DANGER When a communication error occurs on PROFIBUS DP the status of the faulty station is as shown below Create an interlock circuit in the sequence program using the communication status infor mation to ensure the system operates safely Input Xn1 An erroneous output or malfunction may cause accidents The input data from the master station remains unchanged from the data prior to the communication error When the master station becomes faulty the output status of the ME2PB1 L will be as in the parameter settings of the master station When any ME2PB1 L is down the output state of other slave stations will be in accord ance with the parameter settings of the maste
