. 16.17.2.2 LEDs The PROFIBUS Master module provides three PROFIBUS-compliant LEDs that indicate module and network status. PACSystems* RX3i System Manual Section 16 GFK-2314T Sept. 2019 Special Purpose Modules 771 ▪ The green OK LED indicates the presence of power, and completion of backplane reset. ▪ The bicolor Network LED is steadily yellow when the module is holding the PROFIBUS token and able to transmit PROFIBUS telegrams. It flashes yellow if the module is sharing the network with another PROFIBUS master. The Network LED is red if a communications problem such as a connection timeout exists with at least one slave on the network. ▪ The bi-color Mod Status LED indicates module status. When this LED is steadily green, the module is configured and has established a connection with a least one device on the network. If it is flashing green, the module may be waiting for a configuration or may have a firmware problem. If it is flashing yellow, the module is in boot loader mode, downloading firmware, or has a non-recoverable error. The rate of LED flashing provides additional 16 GFK-2314T Sept. 2019 Special Purpose Modules 772 16.18 PROFIBUS Slave Module: IC695PBS301 The IC695PBS301 provides slave communications on a PROFIBUS DP network. The slave module automatically exchanges data with a master device. The slave module has no bus access rights. It can only acknowledge received messages or transmit messages to a master upon request. The PROFIBUS Slave module provides the following PROFIBUS communications features: ▪ Ability to read up to 244 bytes of input data from the network, and send up to 244 bytes of output data ▪ Support for all standard PROFIBUS data rates ▪ Support for DP-V1 Read, Write and Alarm messages ▪ PROFIBUS-compliant module and network status LEDs This module must be located in an RX3i Universal Backplane. Module supports insertion into and removal from an RX3i Universal Backplane which is under power. Refer to Hot Insertion and Removal, Section 2.6.4.1. The PROFIBUS module receives its firmware upgrades indirectly from the host controller CPU using the WinLoader software utility (if the host CPU has a serial port) or using a Web-based tool (if the host CPU has no serial port). Instructions are included with the firmware upgrade kit.23 Figure 405: IC695PBS301 16.18.1 PROFIBUS Slave Module Controls and Indicators 16.18.1.1 Network Connector The PROFIBUS Slave module has a 9-pin sub-D connector for attaching the bus cable. For pin assignments, segment length, cable type and termination requirements, refer to the RX3i PACSystems PROFIBUS Modules User’s Manual, GFK-2301. 16.18.1.2 LEDs PACSystems* RX3i System Manual Section 16 GFK-2314T Sept. 2019 Special Purpose Modules 773 The PROFIBUS Slave module provides three PROFIBUS-compliant LEDs that indicate module and network status. ▪ The green PROFIBUS OK LED indicates the presence of power, and completion of backplane reset. ▪ The bicolor Network LED is yellow when the module is able to transmit PROFIBUS telegrams. It is red if a critical communications problem has occurred. ▪ The bi-color Mod Status LED indicates module status. When this LED is steadily green, the module is configured and has established a connection with the network master.
