57C404COMMUNICATION NETWORK MODULEAUTOMAX5 VDC AT 2.5 AMPS12 VDC AT 53 MA-12 VDC AT 7.5 MAThe products described in this instruction manual are manufactured .by Automation Company.The Network Communications module (M/N 57C404B)provides thenecessary hardware required to transmit control and status databetween two or more AutoMax/DCS 5000 racks to create adistributed control system.The racks that make up the AutoMaxDCS-NET network are called”drops”.Each drop connected to thenetwork must contain a Power Supply module, a Processor module,and a Network Communications module.The network uses a master/slave software protocol.The masterinitiates and controls all transmissions on the network. All transmissions are broadcast, i.e., all modules receive the data packets simultaneously.An address is encoded in each data packetto identify which slave is to respond to a particular transmission.Theslave’s response is also broadcast with all drops receiving the response data packet.
