7 Presentation (continued) Modicon M171/M172 logic controllers General presentation SoMachine HVAC programming software General presentation (continued) Configuration software Modicon M171/M172 logic controllers are supported by a completely intuitive software package SoMachine HVAC (see page 26). b SoMachine HVAC uses 5 languages compliance IEC 61131-3. b This software follows a simple drag and drop function block approach to configuration and is completed with a library of Application Function Blocks (AFBs) and logic functions. b This software runs with 5 programming languages. b Examples: v ST language v FBD language v LD language v IL language v SFC language Available resources on logic controllers for IEC programming Logic controller type M171 optimized M171 performance M172 performance CPU 14.7 MHz 72 MHz, 32 MB RAM 120 MHz, 32 MB RAM Available memory for application 188 kB 1.0 MB Available memory for user interface 1.5 MB Flash memory data 126 MB 5 MB RAM memory (automatic mapping) 2048 B (1024 word) 512 kB (256000 word) 512 kB (256000 word) RAM memory (Modbus mapping) 1024 B (512 word) 10 kB (5000 word) 10 kB (5000 word) EEPROM variables 1024 B (512 word) 28 kB (14000 word) 28 kB (14000 word) Ethernet connection Ethernet access is available on performance logic controllers: b Ethernet access is optional with M171 performance logic controllers by means of a communication module b Ethernet access is embedded with M172 performance logic controllers. Ethernet access enables several functions to M171 and M172 performance logic controllers, such as: > Text e-mail (via NMTP server) > TFTP transfer protocol (for M171 performance only) > DNS > Program transfers (upload/download) > Online debugging > Firmware updates > Parameter management > File management (virtual FTP) > Bridge: specific function allowing PLCs to be configured via the performance logic controllers, on Modbus > WebVisu Communication module (TM171AETH or TM171AETHRS485) and M171 performance logic controller Ethernet connection M172 performance logic controller Ethernet connection . . . . . . . . . . . . . . . . . . . .
