GFK-2458D March 2013 The PACSystems* RX3i High Speed Counter modules provide direct processing of rapid pulse signals up to 1.5 MHz for industrial control applications such as: Turbine flowmeter Meter proving Velocity measurement Material handling Motion control Process control These modules can sense inputs, process input count information, and control outputs without CPU intervention. Module IC695HSC304 provides: 8 high-speed inputs, 7 high-speed outputs, and 1 to 4 counters. Module IC695HSC308 provides: 16 high-speed inputs, 14 high-speed outputs, and 1 to 8 counters. Standard counter types A, B, C, D, E , Z, and a user-defined type can be combined on a module. Module features include: Hot insertion/extraction Terminal Block insertion or removal detection Flash memory for future upgrades Module fault reporting Configurable I/O Interrupts Select module parameters easily changed without re-configuration.
These modules must be located in an RX3i Universal Backplane.
High-Speed Counter modules can be used with a Box-style (IC694TBB032), Extended Box-style (IC694TBB132), Spring-style (IC694TBS032), or Extended Spring-style (IC694TBS132)) Terminal Block. Extended terminal blocks provide the extra shroud depth needed for shielded wiring. See the PACSystems RX3i System Manual, GFK-2314 revision B or later for more information about Terminal Blocks. Terminal Blocks are ordered separately. RX3i High-speed Counter Modules can be hot-inserted and removed following the instructions in the PACSystems RX3i System Manual, GFK-2314. When the module is removed from the backplane or powercycled, it stops counting and accumulated counts are lost.

Output Points versus Temperature
The charts below show thermal deratings for modules IC695HSC304 and IC695HSC308 with maximum loads of 0.75A on each output. For example, if five outputs are used on module IC695HSC304, at 60C the total current of all outputs would be 3.75 Amps. If smaller loads are used on the outputs, then more output channels can be used at a given temperature.

Output Channels For module IC695HSC308, more output channels can be used at the same time at a given ambient temperature when outputs are evenly distributed into two groups. If outputs are either set up as one output group or unevenly distributed between two output groups, fewer output channels can be used for a given ambient temperature. For example, if eight outputs are used on module IC695HSC308, and they are equally distributed between two output groups, the total current of all outputs at 60C can be up to 6 Amps. At a given ambient temperature, if smaller loads are used on the outputs, more output channels can be used.

I/O Status Data Format
The I/O Status Data has the format shown below. Reserved bits are always 0.
The Output Status bits are set regardless of the source (Module Control data or Setpoints).
Module Status Data
The Module Status data provides the CPU with basic diagnostic information about module operation. For both RX3i High-Speed Counter modules the length of this data is 32 bits. During module configuration, it can be assigned to any available references in %I, %M, or %T memory, or to discrete I/O variables.
LEDs Individual green LEDs indicate the ON/OFF status of the modules external input and output points. These LEDs are green when the corresponding points are on. They are off when the corresponding points are off. LED positions are illustrated below. HSC308
Module Status S1 Field Status S2 Terminal Block Present
The Module Status (S1) LED indicates the status of the module. Solid green indicates that the module has been configured. Blinking green indicates no configuration. Blinking amber/yellow indicates a fatal module failure. The Field Status (S2) LED is off if field power is not present. For module IC695HSC308, this LED is off unless power is present on BOTH VA and VB. Solid green indicates that field power is present and that no output circuit faults have been detected on circuits for which fault detection has been enabled in the configuration. If S2 is amber/yellow, field power is present but circuit faults exist for one or more outputs. The modules red/green Terminal Block LED is green when the modules removable terminal block is locked in place. It is red when the terminal block is not locked. The module also sends an Addition of Terminal Block or Loss of Terminal Block message to the RX3i CPU to report the Terminal Block status. During a firmware update, the S1, S2, and TB LEDs blink in a green/off pattern.

Field Wiring: IC695HSC304
Field wiring connections to the module are made to the removable terminal assembly, as described in the RX3i System Manual, GFK-2314. For this module, each row of terminals (eg: 1-18, 19-36) is internally connected. The dual connection points are for wiring convenience; the module cannot be wired for differential inputs. For installations that must meet radiated emissions requirements as in EN 55022, this modules high-speed connections must be made with double-shielded cable. The outside braided shield should be terminated at the entrance to the enclosure and not continue within the enclosure. Both ends of the shielded cable should be grounded. If low-frequency (power line) ground loops are an issue with the application, directly ground one end of the shielded cable and capacitively tie the other end of the shielded cable to ground with approximately 0.01f capacitance. All outputs on module IC695HSC304 form a single output group. Connections

Restrictions and Open Issues in this Release
Description: In applications that include Timed Interrupts or I/O Interrupts, some IC693****** and IC694****** modules in a PACSystems RX3i main or expansion backplane may occasionally be lost during interrupt processing. A fault is logged in the fault table. Recommendations: Minimize the time of individual interrupts and the elapsed time of overlapping interrupt blocks. Cycle power to a lost module to restore operation. If the module supports hot-swapping, that will also restore operation.
