These ports provide serial interfaces to external devices. Port 1 (COM1) is a DCE port that allows a simple straight-through cable to connect with a standard AT-style RS-232 port. It has a 9-pin, female, D-sub connector with a standard pin out. Port 2 (COM2) is a DCE port that is RS-485 compatible. Port 2 has a 15-pin, female D-sub connector. The Ethernet NIU does not have an Ethernet port. Ethernet communications are provided by one or more Ethernet Transmitter Modules (described previously in this chapter) located in the I/O Station. 16.16.7.1 Protocols Supported Protocol Port 1 Port 2 RTU (slave) Yes Yes SNP Slave Yes Yes Serial I/O94 Yes Yes Firmware Upgrade ENIU in STOP/No I/O mode Message Mode (C Runtime Special Purpose Modules 770 Figure 404: IC695PBM300 16.17.1 Features The IC695PBM300 module provides the following features: ▪ supports up to 125 PROFIBUS-DP slaves ▪ supports up to 244 bytes of input data and 244 bytes of output data per slave ▪ Supports up to 3,584 bytes of input data and 3,584 bytes of output data total ▪ Supports all standard data rates ▪ Supports Sync and Freeze modes ▪ Supports DP-V1 Read, Write and Alarm messages ▪ PROFIBUS-compliant Module and Network Status LEDs This module must be located in an RX3i Universal Backplane.
