APPENDIX A: SNAP ETHERNET-BASED BRAIN MEMORY MAP Starting Address Length Type Description FFFF F038 0010 4 UI Set watchdog time in milliseconds (unsigned integer). 0 disables watchdog. FFFF F038 0014 4 UI Set TCP/IP minimum Response Timeout (RTO) in milliseconds. For SNAP Ultimate and SNAP Simple brains, the default is a minimum 100 msec between retries. For SNAP Ethernet brains, the default is a minimum 3000 msec between retries. For a high-speed application such as motion control, you can write a lower minimum RTO to this address. FFFF F038 0018 4 UI Set TCP/IP initial RTO FFFF F038 001C 4 UI Set TCP/IP number of retries FFFF F038 0020 4 UI TCP idle session timeout in milliseconds. 0 = disable Last valid address for this area: FFFF F038 0023 Modbus Configuration—Read/Write Use this area of the memory map for changing the format of Modbus floats. After you change format, be sure to store the information to flash using the Status Write area of the brain (page 107). The Modbus memory map and information are in the SNAP Ethernet-Based I/O Units User’s Guide. Starting Address Length Type Description FFFF F039 0000 4 UI Modbus float format (unsigned integer) 0x00000000 = Big Endian 0x00000001 = Big Endian, word swapped. Most significant bit of float is in most significant register. Last valid address for this area: FFFF F039 0003 108 SNAP Ethernet-Based I/O Units Protocols and Programming Guide
Security Configuration—Read/Write See the ioManager User’s Guide for information on setting up security for the Ethernet-based brain. Starting Address Length Type Description FFFF F03A 0004 4 UI Command processor IEEE 1394 port. Default is 2001. FFFF F03A 0008 4 UI Modbus/TCP port. Default is 502. FFFF F03A 000C 4 UI (SNAP Ethernet and SNAP Ultimate brains only) SNMP port for SNMP agent. Default is 161. FFFF F03A 0010 4 UI (SNAP Ultimate brains only) FTP port. Default is 21. FFFF F03A 0020 4 IP IP Filter Address 0 FFFF F03A 0024 4 IP IP Filter Mask 0 FFFF F03A 0028 4 IP IP Filter Address 1 FFFF F03A 002C 4 IP IP Filter Mask 1 FFFF F03A 0030 4 IP IP Filter Address 2 FFFF F03A 0034 4 IP IP Filter Mask 2 FFFF F03A 0038 4 IP IP Filter Address 3 FFFF F03A 003C 4 IP IP Filter Mask 3 FFFF F03A 0040 30 IP Additional IP Filter Addresses and Filter Masks (4–9) FFFF F03A 0070 4 UI Stop incoming broadcasts. 0 = off (default) Last valid address for this area: FFFF F03A 0073 SNAP Ethernet-Based I/O Units Protocols and Programming Guide 109
