  • Page 98: Access By Request Command

    Access by request command For any data access from the master station to the local station, data can be read or written by handshaking between the "request command execution" flag and the "request command completion" flag. This access is performed using a 2-word word device of the master station. In the double word data, the 4 high-order bits of the first word are assigned to the request command and the 12 low-order bits are assigned to the request code, and the second word is assigned as the word for the set data.

  • Page 99: Request Code

    The numerical value of each parameter corresponding to the request code is treated as real number data without a decimal point. In addition, the minimum and maximum values are determined for LE7-40GU, and when a value exceeding this data is written, it is automatically rewritten to the minimum or maximum value.

    MODBUS/RTU, ASCII (SLAVE) LE7-40GU can be operated as a slave station for MODBUS/RTU and ASCII communication. Data monitoring and parameter writing from a master station for up to 247 slave stations (LE7-40GU units) can be carried out. Precautions • For 5 seconds after turning on the power of LE7-40GU, data from master station will not be accepted.

  • Page 116 ■Connection and disconnection of the cable Spring clamp terminal block is push-in type, therefore, wiring without a tool is possible by simply inserting the connecting terminal to the terminal block. However, the stranded wire does not comply with the push-in type, and a tool is required for connecting cables.

    Terminating resistor settings Be sure to install terminating resistors at both ends of the line. LE7-40GU, the built-in RS-485 port of the CPU module, FX5-485-BD, and FX5-485ADP, have built-in terminating resistors. Set the terminating resistance with the terminating resistor changeover switch.

    Used coil/holding register The coil and holding register used for MODBUS communication of LE7-40GU are as follows. The coil is an area to store bit data and the holding register is an area to store word data. Each slave station has coils from H0000 to H02F and H1000 to H102F as well as holding registers from H0000 to H015F and H1000 to H115F.

    • The numerical value of each parameter is treated as real data without a decimal point. The data defines the minimum value and the maximum value within LE7-40GU and automatically rewrites it to the minimum value or the maximum value when writing data outside the range. At that time, a network alarm "22" is output to the alarm display (H00EB) of the holding register.
