I am using PLC TM221CE16R and SoMachine Basic v1.6. My PLC has firmware 1.6.0.1. I use analog expansion bus, input module TM3AI8. Everything was working fine for 2 hours until suddenly I got next message in SoMachine Basic: I/O expansion configured but is absent or inoperative. I/O expansion bus is not started. Since then ERR LED is always blinking. I already tried deleting program, updating firmware, removing expansion module in configuration page, removing/adding physical module, selected module as Optional, removing battery - nothing helped. If I try removing application, ERR LED is still blinking. Seems like I can't delete previous program, something like config file is burned into PLC. Can anybody please help me? It is really frustrating[url=http://www.99poze.ro/p/33e2aa2086d212e55834ef9267aae0b8.jpg][/url]+[url=http://www.99poze.ro/p/a7a71dd2f63f75db42f2d7489d6a2380.jpg][/url]+[url=http://www.99poze.ro/p/4302ea42402209adf3a1c9bde3502f27.jpg][/url]+ Back to top mikoian Junior Joined: 12 Jan 2018 Posts: 6 Posted: 28/09/2018 16:32    Post subject: PLC TM221CE16R The CPU is PLC TM221CE16R Try extension modules for TM2 to check if works Code: I/O expansion modules can be marked as optional in the configuration. The Optional module feature provides a more flexible configuration by the acceptance of the definition of modules that are not physically attached to the logic controller. Therefore, a single application can support multiple physical configurations of I/O expansion modules, allowing a greater degree of scalability without the necessity of maintaining numeroase application files for the same application. Without the Optional module feature, when the logic controller starts up the I/O expansion bus (following a power cycle, application download or initialization command), it compares the configuration defined in the application with the physical I/O modules attached to the I/O bus. Among other diagnostics made, if the logic controller determines that there are I/O modules defined in the configuration that are not physically present on the I/O bus, an error is detected and the I/O bus does not start. With the Optional module feature, the logic controller ignores the absent I/O expansion modules that you have marked as optional, which then allows the logic controller to start the I/O expansion bus. The logic controller starts the I/O expansion bus at configuration time (following a power cycle, application download, or initialization command) even if optional expansion modules are not physically connected to the logic controller. The following module types can be marked as optional:  TM3 I/O expansion modules %SW118 Logic controller status word Bits 13 and 14 are pertinent to the I/O module status relative to the I/O bus. Bit 13, if FALSE, indicates that there are mandatory modules as defined by the I/O expansion bus configuration that are absent or otherwise inoperative when the logic controller attempts to start the I/O expansion bus. In this case, the I/O bus does not start. Bit 14, if FALSE, indicates that one or more modules have ceased communication with the logic controller after the I/O expansion bus is started. This is the case whether an I/O expansion module is defined as mandatory or as an optional module but present at start-up. %SW119 I/O expansion module configuration Each bit, starting with bit 1 (bit 0 is reserved), is dedicated to a configured I/O expansion module and indicates whether the module is optional (TRUE) or mandatory (FALSE) when the controller attempts to start the I/O bus. %SW120 I/O expansion module status Each bit, starting with bit 1 (bit 0 is reserved), is dedicated to a configured I/O expansion module and indicates the status of the module. When the logic controller attempts to start the I/O bus, if the value of %SW120 is non-zero (indicating that an error is detected for at least one of the modules), the I/O expansion bus does not start unless the corresponding bit in %SW119 is set to TRUE (indicating the module is marked as an optional module). When the I/O bus is started, if the value of %SW120 is modified by the system, it indicates that an error is detected on one or more I/O expansion modules (regardless of the Optional module feature).
