SY/MAX Class 8030 Type CRM-510 Square D Network Interface Module (NIM)

The Schneider Electric / Square D SY/MAX Class 8030 Type CRM-510 Network Interface Module (NIM) is a communications interface, which allows PVs, CRTs, printers, computers, and other SY/MAX Family devices to communicate with each other, exchanging register data and I/O status. When a CRT programmer is connected to the SY/NET network, you can program, monitor, force I/O and up/down load ladder diagram programs to any SY/MAX PC on the Network.

Each Network Interface Module (NIM) can support two devices. Up to 100 NIMs can be connected to a single network, allowing up to 200 devices on one network. With the SY/NET network, you can also link several networks together. Network linking provides network expansion and opens the door for distributed networks and network redundancy.

The SY/NET Network has been designed with simplicity in mind without sacrificing flexibility. Communication between two PCs can be accomplished by utilizing a single rung of the ladder diagram. To communicate the same data over the SY/NET Network all that is needed is to add two route values: source device number and destination device number. Once these route values are added to a communication rung, the same message will then be sent "over the network."

The SY/NET Network, in addition to supporting the SY/MAX Family, also supports communication with the 8881 PC, computers, printers, bar code readers, and other ASCII devices.
