Application memory requirements should be checked against the program size, tag configuration and selected controller firmware.\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eHow many built-in inputs and outputs does 1769-L18ER-BB1B have?\u003c\/strong\u003e\u003cbr\u003eThe controller includes 16 sinking 24 VDC digital input points and 16 sourcing 24 VDC digital output points, providing 32 embedded digital I\/O points in total.\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eWhat power supply does 1769-L18ER-BB1B require?\u003c\/strong\u003e\u003cbr\u003eThe embedded power supply operates at nominal 24 VDC, with a specified input range of 10-28.8 VDC. External power supply wiring and isolation requirements vary by controller hardware series, so the applicable installation manual must be consulted.\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eHow many Ethernet ports does 1769-L18ER-BB1B provide?\u003c\/strong\u003e\u003cbr\u003eIt has two built-in EtherNet\/IP ports. The ports are connected through the controller embedded Ethernet switch, share one IP address and support compatible linear or Device Level Ring network topologies.\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eHow many EtherNet\/IP nodes does this controller support?\u003c\/strong\u003e\u003cbr\u003eThe 1769-L18ER-BB1B supports up to eight EtherNet\/IP nodes. The documented controller connection capacity is 256, although node count and controller connections represent different configuration limits.\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eCan 1769-L18ER-BB1B be expanded with additional I\/O modules?\u003c\/strong\u003e\u003cbr\u003eYes. The controller supports up to eight compatible 1734 POINT I\/O modules on its local POINTBus backplane. Expansion module selection must consider supported firmware, available backplane current and field power requirements.\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between 1769-L18ER-BB1B and 1769-L18ERM-BB1B?\u003c\/strong\u003e\u003cbr\u003eBoth controllers belong to the CompactLogix 5370 L1 family and provide 512 KB user memory, but the 1769-L18ERM-BB1B adds integrated motion capabilities over EtherNet\/IP. The 1769-L18ER-BB1B does not provide that integrated motion functionality.\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eWhat programming software is used with 1769-L18ER-BB1B?\u003c\/strong\u003e\u003cbr\u003eThe controller is programmed using compatible versions of Studio 5000 Logix Designer or earlier RSLogix 5000 software. The engineering software version must be compatible with the installed controller firmware revision.\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eDoes 1769-L18ER-BB1B require a battery?\u003c\/strong\u003e\u003cbr\u003eNo. CompactLogix 5370 controllers use internal energy storage rather than a conventional memory-retention battery. The controller also supports removable Secure Digital cards for nonvolatile storage.\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions and operating temperature of 1769-L18ER-BB1B?\u003c\/strong\u003e\u003cbr\u003eThe controller has a 100 mm width, 130 mm body height and 105 mm depth, with an overall mounting height of approximately 144 mm.
