efesotomasyon.com - Allen Bradley,Rockwell,plc,servo,drive Timer and Counter Instructions How Counters Work The figure below demonstrates how a counter works. The count value must remain in the range of -32,768 to +32,767. If the count value goes above +32,767, the counter status overflow bit (OV) is set (1). If the count goes below -32,768, the counter status underflow bit (UN) is set (1).

efesotomasyon.com - Allen Bradley,Rockwell,plc,servo,drive Protocol Configuration DF1 Half-Duplex DF1 Half-Duplex protocol provides a multi-drop single master/multiple slave network. In contrast to the DF1 Full-Duplex protocol, Protocol communication takes place in one direction at a time. You can use the RS-232 port on the MicroLogix controller as both a Half-Duplex programming port, and a Half-Duplex peer-to-peer messaging port.
Page 507 efesotomasyon.com - Allen Bradley,Rockwell,plc,servo,drive Protocol Configuration Message-Based Polling Mode Message-based polling mode is best used in networks when communication with the slave stations is not time critical and where the user needs to be able to limit when and how often the master station communicates with each slave station.
Page 508 efesotomasyon.com - Allen Bradley,Rockwell,plc,servo,drive Protocol Configuration Standard polling mode causes the master station to continuously send one or more 4-byte poll packets to each slave station address configured by the user in the poll list(s) in round robin fashion – as soon as the end of the polling list is reached, the master station immediately goes back and starts polling slave stations from the top of the polling list over again.

This second use is based on the supposition that if a slave station did not respond the last time it was polled, it may not be able to receive and respond to a MSG instruction now, and so it would most likely process the maximum number of retries and time-outs before completing in error.
Page 510 efesotomasyon.com - Allen Bradley,Rockwell,plc,servo,drive Protocol Configuration Addressing Tips Each station on the network, including the master station, must have a unique address. The address range is 0 to 254, so you can have a maximum of 255 stations on a single telemetry network. Station address 255 is the broadcast address, which you cannot select as a station’s individual address.
Page 511 efesotomasyon.com - Allen Bradley,Rockwell,plc,servo,drive Protocol Configuration DF1 Half-Duplex Master MSG-based Polling Mode Operation With MSG-based Polling Mode, the master device only initiates communication with a slave when a MSG instruction to that slave is triggered in ladder logic. Once the read or write command has been transmitted, the master waits the Reply MSG Timeout period and then polls that slave for a reply to its command.
