90-30 Genius Configuration and Device Present Status Bits
Description
All Genius bus controllers (GBC) must be configured with input and output data lengths matching the I/O device or they will not transfer data. The 90-30 IC693BEM331 GBC lacks the fault table configuration errors of the 90-70 GBC. The quickest way to see if a Genius device is configured correctly is to check if the corresponding GBC Device Present bit is set to 1.
Resolution
The 90-30 GBC is configured with 32 %I status(Device Present) bits for serial bus addresses (SBA) 0 to 31 with the first bit for SBA 0, 2ndfor SBA 1, etc. These Device Present bits are set to 1 for each SBA that is correctly configured (correct data length) and is seen by the GBC during the last 3 token passes. The bit will be set to 0 for devices that are not configured correctly, turned off or not visible due to network problems.
You can determine the Device Present bit address by adding the SBA number to the status address. For example, if the VersaPro GBC Status Reference Type (or Status for LM90), is set to %I401, then %I403 will be 1 if a device at SBA 2 is on the network and properly configured. The bit for the GBC SBA, or Module SBA forLM90, is also set to 1 if the top LED on the GBC is on. In the example, if the GBC is at address 31, the %I432 bit should always be on.
Genius blocks is configured as Input only, Output only or Combo (output with feedback) using the Genius Hand Held Monitor. The Device Type in VersaPro and LM90 must match that configured in the block. Select the %I type for Input, %Q for output or %IQ for combined Input/Output. If the type and length are wrong, the Device Present bit will not turn on. For example, you would select Device Type16%IQ for a 16 circuit block set for Combo. This configures the PLC GBC to transfer 16 %I and 16 %Q bits both starting at the same address.
Differences Between 90-30 GBC and RX3i GBC
Description
What is the difference between a 90-30 GBC (IC693BEM331) vs a RX3i GBC (IC694BEM331)?
Resolution
The IC693BEM331 and IC694BEM331 modules are functionally identical and can be used interchangeably in a Series 90-30 and a PACSystems RX3i rack systems. The differences are the following:
- The IC693BEM331 module has a black cover, to fit the Series 90-30 color scheme, while the IC694BEM331 has a blue cover, to match the PACSystems RX3i color scheme.
- When configuring a PACSystems RX3i rack system in Logic Developer - PLC, select IC693BEM331 or IC694BEM331. When configuring a Series 90-30 rack system, select only IC693BEM331; even if the rack physically contains an IC694BEM331, selecting IC693BEM331 in Logic Developer - PLC is adequate: configure the IC693BEM331 as if it were an IC694BEM331.
The OK LED on IC693BEM331 Blinking in 90-30 System
Description
The Discrete Mixed modules are configured in a remote GBI station and need to communicate with IC693BEM331 in 90-30 system. For these Discrete Mixed modules, like IC200MDD840, IC200MDD841 and IC200MDD843, they all provide IO data length not in a byte-aligned format. When customer configured the data length in IC693BEM331 to match the length provided by the Discrete Mixed modules in 9030 system, the OK LED on IC693BEM331 will blink after downloading the project and running the CPU. This GBI station could not communicate with GBC.
Resolution
In Genius Bus data transmission, the basic unit is byte format. That means, for the discrete mixed modules with non-byte aligned data length, it should be configured in byte-aligned length. For example, if the IC200MDD843 is configured in one of the GBI station, it has 10 DI and 6 DO. In the settings of GBC global data, it should be configured as %I*16 and %Q*8. The next IO module in GBI station will start from %I17 and %Q9.
Note, in RX3i system, no matter IC693BEM331 or IC694BEM331 is installed, during the configuration, if the data is not in byte-aligned format, the length will indicate that in red font and change automatically for byte unit.
Customer Questions and Answers
- Question: What is an IC693BEM331? Answer: The IC693BEM331 is a Genius Bus Controller. It is used to interface a Genius I/O serial bus to a Series 90-30 PLC. The GBC receives and transmits control data up to 128 bytes for as many as 31 devices on the Genius bus.
- Question: How many IC693BEM331s can be installed in a Series 90-30 PLC system? Answer: Up to 8 Genius Bus Controllers can be installed in a Series 90-30 PLC system that has release 5.0 or later Logicmaster 90 software and release 5.0 or later CPU firmware.
- Question: Can a Genius Bus Controller be installed in a system with a GCM? Answer: No, it cannot.
- Question: What are the 2 ways configuration can be done in IC693BEM331? Answer: Configuration can be done using either Logicmaster 90 or the Hand Held Programmer.
- Question: Are there any DIP switches or jumpers to set on IC693BEM331? Answer: No, there are not.
- Question: How can I tell if my device might be faulty? Answer: If you plug it in, power it up, and do not get any lights on at all (like the OK LED), if you have the processor in run mode and you do not get a COM LED, or if you test the module and you do not get a proper response, your device could be faulty.
- Question: What if my IC693BEM331 is not working correctly? Answer: Then your product may be in need of repair.
