The PROFIBUS DP protocol does not define the for- mat of user data, it is only responsible for the transmission of this data. The format of user data may be defined in so called profiles. Profiles can reduce engineering costs since the meaning of application-related parameters is specified precisely. -

Setting up a PROFIBUS Network Section 2-5 Note If the network must be extended beyond the range of the advised cable length, the use of a fibre optic segment to cross the larger distance should be considered. Stub Lines Passive Stub lines (branches from the main line) should be avoided for data transmission speeds of more than 500 kbit/s. -
Page 49: Profibus Cable Connector
A standard 9-pin sub-D plug can only be used if the PRT1-SCU11 is not at the start or the end of a bus segment, or on a stub line at a baud rate of 500 kbit/ s or less. -

Configuration at the Personal Computer. This can be accomplished by either connecting the serial COM port of the Personal Computer to the CS1/CJ1 PLC with a serial interface cable, or use an Ethernet connection between the Personal Com- puter and the CS1/CJ1 PLC via an Ethernet unit. -
Page 51: Defining The I/O Configuration
1. When pressing the Insert button, the selected I/O module will be inserted above the selected module in the Configured Modules list. 2. The selected I/O modules are sent to the slave device, in the same se- quence as selected in the user interface. The sequence determines the target Temperature Controller / R88A-MCW151-E for the I/O data. - Page 52 In this case, refer to the manual of the specific device for details. 4. Also in this window are the maximum values, which can be set, and the to- tals of I/O data that actually have been set. If - while selecting I/O modules - one of the maximum values is exceeded, a warning message will be dis- played.
