• Selecting Cross Reference for an address in the ladder editor is slow when online with a SLC 5/05 processor with a project containing many complex instructions such as EEM, DEM, CEM, and MSG.
• Under Windows Vista or later operating systems, or as an admin on a virtual machine, if User Account Control (UAC) is enabled, you may be prompted to confirm your Administrator privileges when executing certain tasks (like import/export). If you do not have Administrative privileges, contact your System Administrator.
• Online editing of a rung with an LBL instruction fails on an SLC 500 processor in remote run mode if the matching JMP instruction exists in the project and UNTEST is selected. One workaround is to put the LBL instruction on its own rung.
• In a MicroLogix™ 1200 or MicroLogix 1500 project, if a CLR instruction with an HSC:0.ACC or HSC:1.ACC operand exists in the rung with a nested branch (for example: BST XIC B3:0/0 CLR HSC:1.ACC NXB ADD 0 N12:1 N7:0 BND), the project verification will fail and a compiler error will be displayed.
• RSLogix Micro will not allow the use of a Floating Point constant in an SCP instruction.
• With a MicroLogix 1500 LRP Series C Channel 1 Radio modem, the broadcast message destination node 1 is not accepted when verifying the project. The error message invalid local DH-485 Station Number (0-254) displays even though 1 is a valid local DH-485 station number when Channel 1 is set for DF1 Radio modem and a broadcast message is requested.
• In order to support the MicroLogix 1100 Series B controller, RSLogix Micro handles PTO and PWM frequencies (PTO.OF, PTO.OFS, PTO.JF, PWM.OF, and PWM.OFS) as unsigned 16-bit integers (0 - 65535) for MicroLogix 1100 Series B. If you are using an older version of RSLogix 500 (version 7.0 and version 7.10) with the MicroLogix 1100 Series B controller, there will be compatibility issues. These include:
  • RSLogix Micro display issues: Because an older version of RSLogix Micro treats PTO/PWM frequencies as signed integers, if you upload a program from a MicroLogix 1100 Series B controller into the software, a negative frequency value may be displayed. For example, 40 kHz is 0x9C40 in hexadecimal. The hexadecimal value 0x9C40 is 40000 in unsigned integer, but -25536 in signed integer.
  • Instruction issues: All instructions in MicroLogix controllers treat integers as signed integers. Therefore, unsigned integers in PTO/PWM function file elements need to be treated carefully when they are used in the variables for instructions. An undesired result may be returned or math overflow may be detected during instruction executions. A workaround should be used such as copying PTO/PWM frequencies to long integer before manipulation. For greater detail refer to Appendix F: How to use 40kHz PTO/PWM of MicroLogix 1100 Series B Controller, publication 1763-RM001.
• If the address description in a data file is changed, the description in the Trend applet cannot be updated.
• When changing DNP3 Data Set configuration from Data Element (DAEL) to Prototype (PTYP) several times, RSLogix Micro may stop responding. In this event, restart RSLogix Micro.
