Chapter 7: Appendix

The AB rate monitor uses a Micrologix 1500 LRP processor that communicates with the outside world 
using DF1 protocol with Ethernet hardware.  Its Ethernet speed is 10/100 Mbits/second.  The rate monitor 
must be purchased from ACS with the Ethernet option.  If this was not done at the time of purchase it can 
be added afterwards by consulting the factory.  The rate monitor has a programmable IP address and 
subnet mask that can be programmed from the Panel View that comes with the GH Hopper (refer to GH 
Hopper manual). 

Ethernet is the standard that we support, but AB also supports Device Net, DF, and DH485 protocol to 
these PLCs.  Refer to AB documentation. 

The DF1 port is 19200 baud with no parity and a source ID of 1.  This is usually not important since you 
will be communicating with the Ethernet module instead of directly with the DF1 port.  Be sure that the 
DCOMM light is on by depressing the COMMS switch under the PLC front panel.  After this light is on 
then you can touch the ACS icon and enter “5413”, then select Ethernet Setup, program in you IP address, 
click “send config to module”, and then wait about 45 seconds for it to program the new IP address.  If 
you cannot ping the module then reboot the rate monitor and try again 45 seconds after booting. 

 

Below are the items that can be accessed for the GH Hopper: 
 
GENERAL HOPPER INFO 

1.  plc_version,n23:0 (xx.x) 
2.  hopper_weight_percent,n20:1 (0-1150), easy to use scale to show weight 
3.  total_weight_minus_tare ,f30:16, this is the material weight 
4.  reload_output,o:0/0, to show reloading 
5.  extruder_running_graphic_cycle,T4:9/dn, use this to toggle between 2 graphics (off=show graphic 1, 

on=show graphic 2) 

6.  hauloff_running_graphic_cycle,n9:9, use this to toggle between 2 graphics (n9:0=0 then hauloff is not 

used, n9:0=1 then show graphic 1,n9:0=2 then show graphic 2) 

 

HOPPER MODE STATUS 

1.  ramp_to_stop_engaged,b50:6/0 
2.  monitor_mode_engaged, b50:6/1  
3.  control_by_rpm_engaged, b50:6/2 
4.  control_by_weight_engaged, b50:6/3 
 

HOPPER MODE CONTROL 
1.  ramp_to_stop_pushed,b50:5/0 (toggle this bit to stop line) 
2.  monitor_mode_pushed, b50:5/1 (toggle this bit to put in monitor mode) 
3.  control_by_rpm_mode_pushed, b50:5/2 (toggle this bit to put unit in rpm mode) 
4.  control_by_weight_mode_pushed, b50:5/3 (toggle this bit to put unit in weight mode) 

 

HOPPER ALARMS 

1.  alarm_number,N26:0 (see below for description) 
2.  hopper_low_level_alarm,b28:0/1 
3.  hopper_out_of_material_alarm,b28:0/2 
4.  hopper_over_filling_alarm,b28:0/3 
5.  inventory_cleared,b28:0/4
