115 VAC/125 VDC Isolated Genius I/O blocks have four isolated groups of two I/O circuits, each rated to operate at a nominal 115 volts AC or 125 volts DC. 115VAC/125VDC 8 Circuit Isolated I/O Blocks (IC660BBS102 and BBS100). These blocks report a Failed Switch diagnostic if any output s commanded state is not the same as the actual state of the block s own internal switch. 115 VAC/125VDC Isolated I/O Blocks without Failed Switch Diagnostic (IC660BBS103 and BBS101). For applications where field wiring such as manual switches will be wired in parallel with block outputs. These blocks ignore differences between an output s commanded state and the actual state of the block s internal switch. Isolation is rated to withstand 250 VAC/VDC continuous between any group and ground or between any two groups. Transient rating is 2000V peak for 10 sec. Control power for the block is tapped off the input/output device voltages wired to the terminals. The block has terminals for a separate power source for the internal electronics. The block power supply can be independently either AC or DC. The block need not be powered in the same manner as the circuits. Features Configurable features of these blocks include: AC/DC circuit voltage Output Pulse Test capability Selectable Input Filter Time from 10mS to 100mS Output powerup defaults Output Hold Last State or default CPU Redundancy type Bus Switching Module control 2A/Pt Max 15A Max Total 115V 50/60 Hz 125 VDC GE Fanuc GENIUS Electronic fusing is built into each circuit used as an output. The circuit is shut down 5mS after a short occurs. It can be easily restarted from a Hand held Monitor or from the CPU. The blocks perform these additional diagnostic checks: Overtemperature Open Wire for tristate inputs. Detection of loss of I/O power on pairs of circuits Overload Detection and Shutdown No Load Detection 5 GEK-90486D-2 Chapter 5 115 VAC/125 VDC Isolated I/O Blocks 5-3 Compatibility Hand-held Monitor: These blocks are fully compatible with a Hand held Monitor identified by catalog number IC660HHM501. They may also be used with HHM500. HHM501 is required to change baud rate configuration, or to configure the block for redundancy. Bus Controller: The blocks may be used with any GE Fanuc Genius bus controller, PCIM or QBIM. I/O Blocks: These blocks are backward compatible with previous block versions (IC660CBS100, IC660BBS100, and IC660BBS101). They may be used as replacements for earlier versions. However, their Terminal Assemblies are not backward compatible, as explained below. Electronics Assembly: Electronics Assembly IC660EBS100H may be used to replace any Electronics Assembly IC660ELS100 or IC660EBS100. Electronics Assembly IC660EBS101C may be used to replace any version IC660ELS100, EBS100, or EBS101. These Electronics Assemblies draw lower leakage current (7mA) than earlier versions (which drew 13mA). Terminal Assembly: The Terminal Assembly for these blocks (IC660TSS100E) is not compatible with some earlier versions of their Electronics Assemblies (IC660EBS100A to G, or IC660EBS101A or B). If Terminal Assembly IC660TSS100E will be used to replace an earlier version of the Terminal Assembly, it will also be necessary to upgrade the Electronics Assembly. This can be done by replacing the entire Electronics Assembly with version IC660EBS100H or IC660EBS101C, or later. It can also be done by upgrading the Electronics Assembly firmware using one of these update kits: 44A286357 G06 (with Failed Switch Diagnostics) 44A286390 G03 (without Failed Switch Diagnostics) Opto couplers Circuit LEDs Each circuit has its own LED. If the circuit is configured as an input, the LED indicates the presence of threshold voltage at the input terminal. If the circuit is configured as an output, the LED indicates the state commanded by the CPU. Inputs and Outputs An Isolated Block can be configured as an inputs only, outputs only, or combination block. For a new block, the default is inputs only. Regardless, the block always broadcasts one byte of data each bus scan, and accepts one byte of data each bus scan. If the block is configured as a combination block, circuits can be any mix of inputs and/or outputs. The block will use 8 input references and 8 output references. The actual state of each output will be returned to the CPU in the corresponding input reference location. The CPU can monitor the feedback state to verify (after an appropriate delay) that the output switching device has operated properly and that the load has the proper voltage and current applied. If the block is configured as an inputs only block, all circuits must be regular inputs or tristate inputs. The block will use 8 input references and NO output references. If the block is configured as an outputs only block, all circuits must be be outputs; no feedback analysis will be performed. The block will use 8 output references and NO input references. Appendix B shows reference usage for a Series 90, Series Six, or Series Five PLC. Hand held Monitor I/O Display The Hand held Monitor displays the I/O types (line 3) and current states (line 4) of all circuits on the Monitor Block screen. REF 1 8 O 1 2 3 4 5 6 7 8 O O O O O O O O 1 1 0 1 0 1 0 0 Individual circuits are displayed on the Monitor/Control Reference screen (which also shows a circuit s fault and force status). 5 5-6 Genius I/O Discrete and Analog Blocks User s Manual September 1993 GEK-90486D-2 Diagnostics 115 VAC/125 VDC Isolated I/O blocks perform the following diagnostic checks. The block reports all faults to the Hand held Monitor, and takes appropriate corrective action. Individual circuits can be configured not to send diagnostic messages to the CPU if a fault occurs. If the CPU requests diagnostic information from the block using Read Diagnostic datagrams, the block returns current diagnostics for all circuits, including any with CPU fault reporting disabled. Loss of I/O Power Diagnostic An Isolated I/O block operates as long as power is supplied to terminals 5 and 6. The Loss of I/O Power diagnostic, which is unique to these blocks, indicates that one pair of circuits is disconnected from field power. If either circuit of the pair is an input, the block sets it to 0. If either circuit is an output, the block turns it off. The block automatically sends a Loss of I/O Power diagnostic message to the Hand held Monitor. However, the message is not sent to the CPU unless the block is Pulse Tested. The Unit OK LED does not blink. When I/O power is restored, the circuits begin operating as soon as power reaches the minimum level. If I/O power to the block itself is lost, the block cannot send diagnostic messages to the CPU. The bus controller responds as it would to any other loss of block condition. Overtemperature Diagnostic Each circuit has a built in thermal sensor. If the block s internal temperature exceeds 100C, the block sends an OVERTEMPERATURE message and turns off the circuit to protect its internal electronics. This diagnostic is always performed for both inputs and outputs. Short Circuit Diagnostic Automatic output diagnostic. Output circuits are always protected by a short circuit level sensor at the switching device. An output will turn off within several microseconds after the instantaneous current exceeds 25 amps at turn on, or 15 amps after 2 cycles AC or 10mS for DC. The block will try to restart the load; if several attempts are unsuccessful, the output circuit is forced off and the block sends a SHORT CIRCUIT message. To restore normal operation, the cause of the current surge must be removed, then the diagnostic must be cleared from the HHM or the CPU. |
